State of the Ocean (SOTO) State of the Ocean (SOTO) provides near real-time data that are displayed in a Google Earth environment and annotated to give context descriptions of the ocean’s features and events using KML overlays (ice extent, hurricane tracks, clouds). It provides data layers for satellite derived sea surface temperature and anomalies, sea surface height anomalies, wind vectors, and ocean color. PO.DAAC
TerraViva! SEDAC Viewer The TerraViva! SEDAC Viewer is a standalone software application (Microsoft Windows-based) that enables the visualization and integration of hundreds of socioeconomic and environmental variables and layers, including many data sets from SEDAC and a range of satellite-based data. TerraViva! is of primary interest to researchers and analysts working in a variety of areas, from environmental and ecological sciences to the social and health sciences. Along with the many global data sets the 2011 update includes 51 ready-made maps, ten GeoData indicator collections with hundreds of variables, and other features – scatter plots, tabular data display, map image production, and Web-based download of additional data layers.

TES Search and Subset Tool This tool enables a more sophisticated approach to selecting and ordering TES global survey standard data by date, time and geolocation. Data products can be subset by parameter and geolocation. Output can be requested in HDF-EOS or netCDF. ASDC
view_hdf A freely available IDL-based display and analysis tool for accessing data stored in HDF and HDF-EOS format. Variables from either Science Data Sets or vdata structures in a HDF file, can be subset, rendered as two and three-dimensional graphics, and plotted as geolocated data onto various world map projections. Other features include multiple variable plots, difference plots, and simple statistics. ASDC
Way Point Planning Tool The Waypoint Planning Tool (WPT) is a Java application used to specify aircraft flight tracks through an interactive point-and-click interface. Individual flight legs are automatically calculated for altitude, latitude, longitude, leg distance, cumulative distance, leg time, cumulative time, etc. The resultant flight plan can then be posted to the Google Earth-based RTMM for all interested scientists to view and track actual flight progress compared to the planned flight track.
