The Goddard Earth Sciences Data and Information Services Center (GES DISC) has teamed with nine of other NASA Earth Observing System Data & Information System (EOSDIS) Data Centers to develop the Simple Subset Wizard (SSW), which is designed to provide a simple, unified user interface for submitting subset requests for data. The SSW uses an agent-based architecture to interface with the diversity of subsetters across EOSDIS. To date, eight of the data centers offer subsetting services through SSW, with two more soon to come.
The SSW currently has 11 agents to interface with different subsetters, which support the subsetting of 217 EOSDIS data sets. The SSW provides the capability to subset by either temporal range or spatial region, although not all subsetters have both of these capabilities. Furthermore, some subsetters will impose limits on the number of files that can be subsetted in a single request.
The image at right shows the SSW input screen. Shown below is an example of the output results (click to see larger). The Atmospheric Infrared Sounder (AIRS) AIRX3ST8 v005 data set surface temperature data parameter was subset for this example. The results were requested in ASCII text format; the other option is netCDF output.
