New study questions the accuracy of satellite atmospheric temperature estimates
▻http://www.theguardian.com/environment/climate-consensus-97-per-cent/2014/nov/07/new-study-disputes-satellite-temperature-estimates
In fact, for the time period 1987–2006, the [increase in] temperatures among the four groups that collect satellite data ranges from 0.086°C per decade to 0.22°C per decade. In more recent years, the trend is much reduced, and for two of the leading satellite groups (University of Alabama at Huntsville and Remote Sensing Systems), temperatures are basically flat.
The recent flatness in satellite temperatures as surface temperatures continue to rise has presented a quandary for scientists. Are both results real? Is there some reason they diverge? Is one measurement more accurate than the other? This is one of the areas of very active research.
A contribution to this question appeared last week by researcher Fuzhong Weng and his colleagues. The paper, published in Climate Dynamics, claimed to find the reason for much of that difference – the authors report that the satellite trends could be off (too cold) by perhaps 30%. If true, this work would go a long way toward reconciling the differences between surface and satellite measurements.
[...] Of course, whenever a study that is this significant is published, there is deserved skepticism. We have to be guarded in our acceptance until further work is done and until other teams have had a chance to review the findings.

The ability of scientists to make accurate predictions about future effects of CO2 will be boosted by vital data from a US satellite being launched to take a detailed inventory of the planet’s sinks and sources of carbon.
LONDON, 28 June, 2014 − The US space agency NASA is about to send up a satellite that will provide vital data for predicting future effects of CO2 by taking the measure of the planetary carbon budget.
#satellites #climat #co2 #espace
Petit stress pour la lancer (le 1er juillet) toutefois, vu que le lancer du premier OCO avait échoué en février 2009. Après l’échec du premier, ils ont reconstruit l’instrument à l’identique faute de moyens, donc c’est la même technologie qu’il y a 5 ans, ce qui est un peu dommage. L’équipe OCO a eu le temps de se préparer et s’était reportée sur l’analyse des données du satellite japonais GOSAT qui a des caractéristiques similaires. Du coup ils devraient être prêts à fournir des estimations de CO2, de ses sources et puits sassez rapidement. J’imagine leur impatience et leur nervosité en ce moment.

U.S. Government Eases Restrictions on DigitalGlobe
▻http://www.spacenews.com/article/civil-space/40874us-government-eases-restrictions-on-digitalglobe
Previously, Longmont, Colorado-based #DigitalGlobe was not permitted to sell its sharpest satellite images to non-U.S. customers. Some of the company’s existing satellites can collect images at resolutions sharper than 50 centimeters, but prior to the ruling, it could only sell that information to the U.S. government.
[...]
DigitalGlobe’s planned WorldView-3 satellite, which will feature a ground sampling distance of 31 centimeters, is slated for launch Aug. 13 or 14 from Vandenberg Air Force Base, California, the company said. For that satellite, “updated approvals” will permit DigitalGlobe to sell black-and-white images with 25-centimeter resolution, along with color images at 1-meter resolution, to all customers six months after it is declared operational.
... Ceci, le lendemain de l’annonce de l’achat de Skybox par Google. Mais les relations avec DigitalGlobe semblent bonnes.
Google recently signed a 10-year imagery supply contract with DigitalGlobe valued at an estimated $10 million to $20 million per year, Quilty noted. While Skybox’s planned constellation of 24 satellites will offer high revisit rates – Skybox currently has one satellite on orbit – DigitalGlobe has advantages in terms [of] better imagery resolution, accuracy and diversity of spectral bands, he said.
Moreover, Quilty said, a Google-owned Skybox is not likely to threaten DigitalGlobe’s core U.S. government business.
Ruling on sharper satellite images poses a privacy problem we can no longer ignore

La constellation de #satellites sera placée à une orbite basse et connectée à un réseau de stations au sol.
Station = terminal ou relais ? Car s’il faut des relais au sol, ça me semble moins intéressant pour « lutter contre la censure ».
Au début, les premiers satellites ne pourront diffuser qu’une communication unidirectionnelle, avant de passer à une communication bidirectionnelle lorsqu’ils seront suffisamment nombreux.
Forcément, si c’est du wifi et sans relais au sol, ça ne peut être qu’unidirectionnel... Et donc je vois pas comment on lutte plus efficacement et significativement contre la censure quand les requêtes des utilisateurs passent encore par le réseau « national ».
Cependant, l’ensemble des sites Web ne seront pas accessibles, la priorité étant donnée aux sites proposant des actualités internationales indépendantes, à l’encyclopédie #Wikipédia ou aux services d’éducation en ligne par exemple.

Stop the palm oil industry’s assault on the Amazon
▻https://www.rainforest-rescue.org/mailalert/933/stop-the-palm-oil-industry-s-assault-on-the-amazon#more
In 2000, the Peruvian government declared oil palm plantations in the Amazon region to be in the national interest. Melka’s plantation companies are said to have already purchased 60,000 hectares of primary rainforest from the government in the Loreto region alone and requested a concession to clear more than 100,000 hectares of virgin forest in Loreto and in the neighboring region of Ucayali.
The responsible politicians and officials now claim to have been unaware of the deforestation by Melka’s plantation companies. Since Peru prohibits the clear-cutting of primary forest for oil palm plantations, the companies first clear the land without a permit and then offer to reforest it with oil palms.
In recent months (...) life in Peru’s Amazonian lowlands has been marked by fear and turmoil. Foreign speculators have begun with large-scale clear-cutting – initially in secret. Promises, threats and blackmail have prompted farmers to sell their rainforest plots to the plantation companies at well below their value.

The Big Atlas of LA Pools
▻http://benedikt-gross.de/log/2013/06/the-big-atlas-of-la-pools
The “Big Atlas of LA Pools” is about the process of mapping and map-making in the contemporary age of #big_data, #open_data, #crowdsourcing, and citizen science.
Mappers spot all the pools in L.A. Basin
▻http://www.latimes.com/local/la-me-c1-swimming-pools-20131202-dto,0,198951.htmlstory
The two men started by sending two sets of satellite photos from the federal National Agriculture Imagery Program — one a true color composite, the other a false-color version to make the pools easier to spot — to a crowd-sourcing service in India. They paid workers $300 to draw the outline of every pool shown in the pictures onto a computer program.
They then spent an additional $350 to have the initial count double-checked by Amazon Mechanical Turk, another crowdsourcing service. Workers there inspected images of each swimming pool’s location to confirm it was a body of water and not, say, a house with a blue roof.
The duo used eight publicly available databases, including latimes.com’s Mapping L.A., for the project. Other data sets used included the county’s parcel boundaries service, the Los Angeles County sheriff’s crime database, the assessor’s data set and a database that contained those donating money during the Proposition 8 campaign on gay marriage and the Megan’s Law list of registered child molesters.
[...] Lee agrees: “The feeling that this is occurring with armies of people and computers doing the exact same exploration at a higher scale is frightening.”

While the dishonest and the stupid are attempting to railroad everyone into military endeavours devoid of public benefit, let us remember that France stood out of the Iraq war because it had independent orbital imaging capabilities showing that the WMD claims were nonsense... Meanwhile, the USA took for a ride all the blind ones who had decided that US imagery was cheaper and good enough.
Military sovereignty is also about being able to remain peaceful - let us remember that next time the time for budget cuts come: ▻http://fistfulofeuros.net/afoe/spies-for-europe
–----------------------------------------------------------
The original statement is in this Ken Silverstein piece (▻http://harpers.org/sb-creating-th-1149534425.html):
“They say everyone else was wrong,” said this former official, “but we conditioned them to be wrong. We spend [tens of billions of dollars per year] on signals intelligence and when we reach a conclusion, the people who spend less than that tend to believe us. They weren’t wrong, they chose to believe us. The British, Germans, and Italians don’t have all those overhead assets, so they rely on us. Historically they have been well-served, so they believe us when we tell them the earth is round. The French have their own assets—and guess what? They didn’t go with us”
Guilhem Penent, of France’s IFRI and IRSEM thinktanks, writes in the Space Review (▻http://www.thespacereview.com/article/2340/1) as follows:
“Regarding outer space, France’s main objective is to perpetuate its autonomy and national sovereignty. As sovereignty is the state of determining itself based on its own will without depending on other nations, satellites are, first and foremost, the guarantee of France’s autonomy in assessment and thereby in decision-making”
The decision not to follow the US in 2003 was thus taken by then President Jacques Chirac in accordance with intelligence based for the most part on Earth-imaging satellite HELIOS 1, whose findings were in contradiction which was being said at the UN Security Council. When the war in South Ossetia broke out in 2008 between Russia and Georgia, then President Nicolas Sarkozy, as chair of the Presidency of the Council of the European Union (EU), used images provided by HELIOS 1 and HELIOS 2 to deny Russia’s allegations about the withdrawal of its troops when those troops were actually progressing southward.
This is the first public confirmation, I believe, that the French did in fact stand out of the Iraq war because HELIOS imagery showed that the WMD claims were nonsense

NGOs are also using this information to track humanitarian crises, and in one case, to document the latest tactics around elephant poaching to fund an army in the Congo.

There has been a fire outbreak in a well at the Bulla-Deniz gas condensate field on the Caspian Sea shelf. According to a report posted on the website of the State Oil Company of Azerbaijan (SOCAR), which is the operator of the field, the fire has engulfed exploration well No 90 in the northeast wing of Bulla-Deniz.
According to SOCAR, the fire broke out on Saturday night during drilling at a depth of more than 5.8 thousand meters. “At 23:30 local time (22:30 MSK) a wild gas blowout occurred after which the fire started,” the statement says. It says that all the workers who were on the platform were evacuated to the shore.
“At present, fire-fighting vessels that have surrounded the platform control the situation. The fire extinguishing operation will begin after the plan for shutting down the well is prepared,” SOCAR stated.
The causes of the fire outbreak are being investigated.
The Bulla-Deniz field is located in the open sea at a distance of 80 kilometres from Baku. It was discovered in the mid-1970s. The sea depth at the field is about 26 metres.

APA - SOCAR vice-president : Overcoming of accident in Bulla-deniz gas field is realized at the cost of internal forces’ - INTERVIEW
▻http://en.apa.az/news/197969
As SOCAR President Rovnag Abdullayev told journalists yesterday, fire-extinguishing is not a big problem.
En fait, le problème c’est que la SOCAR aimerait bien ne pas trop démolir le puits existant ( segregation )…
Preparation works on segregation have already been started in the well. The initial actions comprise to approach the well and clean the broken equipment. Thereafter, we will begin to work for extinguishing and segregation of it. I want to note that the Commission continues its work on a daily basis. Specific measures will be defined for each day depending on the situation.
On réfléchit, on se prépare et on va bientôt s’attaquer au problème.
Pas besoin des experts étrangers.
Q. Media reports that BP-Azerbaijan is closely participating in the fire-extinguishing. What can you say about their role in this situation?
- BP-Azerbaijan company is one our main foreign partners functioning in Azerbaijan and has been cooperating with the State Oil Company for years. In case of this accident, they addressed us that they are ready to participate in the elimination process of the accident. Taking into account the experience of BP gained in the Gulf of Mexico, we accepted their proposal. We also invited their specialist to the meeting yesterday. Opinions of BP’s experts were also taken into account. It became clear that there is nothing in their approach to the situation. Other Azerbaijan-based foreign oil companies have offered their help in fire-extinguishing. SOCAR appreciates urgent reactions of BP and other foreign partners and their efforts to help us in the situation and thanks their leaderships. Consequently, the proposals of Azerbaijani experts reflect the real situation more clearly. We prefer to solve the issue at the cost of internal forces. I’m sure that Azerbaijani experts will decently overcome this problem.

The fire on the Bulla-Deniz gas field that broke out at the beginning of the night of Aug. 18 is still going on. According to the spokesman for SOCAR Nizamaddin Guliyev, the order of the President of SOCAR established a commission to deal with the accident. Estimates of the economic and environmental consequences of the accident will be made later.
Meanwhile, representatives of the Ministry of Environment are monitoring at the scene to assess the impact of the fire on the environment. Experts estimate the impact as “insignificant.”
The representative of the Environment Ministry Mirsalam Ganbarov told Turan that for security purposes, to approach the scene of the fire is impossible, and the surveillance and monitoring are conducted in the distant way. Given that methane gas burns, any damage to the environment has not been registered, he said.

Fire continues burning on the well No 90 on the Bulla Deniz field owned by State Oil Company of Azerbaijan (SOCAR) for three months.
On August 17, 2013 at 11.30 p.m. local time, 80 km south of Baku, there was an accident on the exploration well on the depth of 5868 meters under high gas pressure. The well flowing has caused fire, which continues till now. According to SOCAR’s estimates, the gas pressure was so high that every day over 5-6 million cub.m. of natural gas was burnt. Then the gas flow decreased to 2.5-3 million cub.m.
SOCAR said that it has no problems with fire extinguishing. The main goal is to save the exploration well, because there is a possibility to use the equipment left on the well after extinguishing and complete drilling. A lot of money and over a year was spent for drilling of a deep well.
Ça fait donc un tout petit peu plus de 2 mois que l’extinction de l’incendie ne pose aucun problème…

À chaque fois, on commençait à m’expliquer que c’était normal, que c’était une torchère… et quand je montrais la vidéo où, heureusement, on distingue parfaitement bien les couleurs azerbaïdjanaises sur la cheminée du bateau arroseur, on me redemandait comment je le savais.

les instruments embarqués à bord des satellites ont majoritairement le regard braqué vers les pays qui les ont financés. Et quand ce n’est pas le cas et que les données sont disponibles, parfois gratuitement, leur coût de traitement et d’interprétation peut s’avérer rédhibitoire.
« Le recours à ces technologies serait pourtant rentable dans le cadre d’une politique de développement », estime Didier Rigal, d’Astrium Géo-Information Services, une filiale du groupe EADS. « Les programmes d’observation de la terre tel SPOT [Satellite pour l’observation de la Terre] ont été lancés [en 1985] grâce des investissements publics, poursuit-il. Aujourd’hui, ces programmes ont été privatisés. L’équation économique qui permettrait la dispersion des données n’est plus la même. »

#Espace et #risques : le problème des #débris spatiaux pour les #satellites, mais pas seulement.
Ces objets représentent une double menace. D’abord, logique et gaulois, celle de « leur retour sur Terre », explique Christophe Bonnal, expert du Centre national d’études spatiales (Cnes), l’agence spatiale française. Pour ne pas l’oublier, il garde dans son bureau une sphère de titane d’un mètre et 50 kg, un réservoir d’hélium d’une fusée Ariane tombé dans un jardin en Ouganda. « Il y en a 200 comme ça dans l’espace, qui retomberont on ne sait quand, ni où. Et ce n’est qu’un exemple. Il y a aussi des turbopompes, des tuyères, 296 troisièmes étages du lanceur russe Cosmos 3M qui pèsent près de 2 tonnes », avertit l’ingénieur qui fait partie du groupe d’experts mobilisés par le Comité interagences sur les débris (IADC). « En moyenne, il tombe un objet lourd tous les trois jours, et un d’au moins 300 kg par mois », précise-t-il.
Jusqu’à présent sans faire de victime. Même les milliers de morceaux de la navette Columbia tombés sur le territoire des Etats-Unis en 2003, lors de son explosion au retour dans l’atmosphère. Un peu gêné, l’ingénieur avoue que, statistiquement, « c’est un coup de chance, puisque, d’après nos calculs, cela aurait déjà dû se produire ». Un groupe de travail se serait réuni au #Cnes sur le thème « qu’est-ce qu’on dit aux gens le jour où un de ces débris tue quelqu’un en France ? » Le flux de ces retombées varie au fil de la météo solaire. Lorsque l’astre est très actif, comme depuis un an et pour quelques années, il dilate la thermosphère, entre 90 et 500 km, ce qui freine les satellites et accélère leur retombée.

Satellites critical to the ability of meteorologists to build accurate long-term forecasts are expected to fail in 2016, while replacements won’t go online until the following year at the earliest. The gap in coverage will mean meteorologists will receive half the data they get now, giving a less clear picture of the globe and imperiling their ability to predict the weather.

la défense américaine invite les astronomes amateurs à localiser les débris en tout genre qui se baladent dans l’#espace et perturbent le parcours des #satellites et d’en établir la #cartographie
NASA estimates more than 500,000 pieces of hazardous space debris orbit the earth, threatening satellites that support peacekeeping and combat missions. These objects include spent rocket stages, defunct satellites and fragments from other spacecraft that are the result of erosion, explosion and collision. A collision between one of these small pieces of debris and a satellite could release more than 20,000 times the energy of a head-on automobile collision at 65 mph. To help address the threat, DARPA created SpaceView, a space debris tracking project that provides amateur astronomers with the means to make a difference. Amateur astronomers will have their first opportunity to sign up in person for the program at the Arizona Science and Astronomy Expo in Tucson, November 10-11, 2012.
The vision behind the SpaceView program is to provide more diverse data to the Space Surveillance Network (SSN), a U.S. Air Force program charged with cataloguing and observing space objects to identify potential near-term collisions. SpaceView hopes to achieve that goal by engaging U.S. amateur astronomers by purchasing remote access to an already in-use telescope or by providing a telescope to selected astronomers. When a telescope that is provided by the program is not in use by the SpaceView program, DARPA will provide its use for astronomy and astrophotography.

SpaceView seeks to provide the amateur astronomer with the opportunity to make a difference in the task of protecting our nation’s space assets. We are actively seeking information from individual astronomers about their equipment, sites, and observing habits.
We are also exploring a mutually beneficial partnership that can last for the long term. This could potentially include time-sharing on telescopes, upgraded hardware at the astronomer’s site, or financial compensation.
