Abstract: AMSU-A is a cross-track, line-scanned instrument designed to measure scene radiances in 15 discrete frequency channels which permit the calculation of the vertical temperature and moisture profiles from about 3 millibars (~45 km) to the Earth's surface. Each scanline contains 30 overlapping cells, each with a resolution of ~3.3 degrees (50 km at nadir). This yields a swath width of 2343 km (96.66 ... degrees). This data set is maintained at the Global Hydrology and Climate Center located in Huntsville, Alabama, for use by scientific researchers. In an effort to provide wider dissemination of this information, ITSC has released an OGC-compliant web map service that maps AMSU-A swath data based on specific spatial and temporal requests criteria. A web map service returns the image of one specific data layer that users/applications can then overlay or merge with other data layers to create composite maps. The Open Geospatial Consortium (OGC) is an international consortium of industry, government agencies and educational institutions striving to standardize interfaces and protocols for using geospatial data.
