A new infrastructure system has been designed to assist a wide range of users around the world with data access and evaluation, as well as with scientific exploration and discovery. This system, the Geospatial Interactive Online Visualization and Analysis Infrastructure (Giovanni), was developed by the NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC).
The paramount goal of Giovanni is to provide scientists and the public with a simplified way to access, evaluate, and explore NASA satellite data sets. Here we describe the latest capabilities of Giovanni with examples, and we discuss potential future plans for this innovative system.

Giovanni provides access to numerous satellite data sets, concentrated primarily in the areas of atmospheric composition, atmospheric dynamics, global precipitation, hydrology, and solar irradiance.
More than 1,600 variables are currently available in Giovanni. The Web interface has keyword and faceted search capabilities for locating variables of interest (Figure 1). For example, a search for “precipitation” returns more than 100 related variables. A user performing a faceted search can filter for variables based on satellite missions (TRMM, Global Precipitation Measurement (GPM)), instruments, spatial or temporal resolution, or other categories.
