Channels Available for Subsetting Services
Users can either specify any channel for the subsetting request or choose a pre-defined set as shown in the table below (Courtesy of Evan Manning, NASA/JPL). This will make it easier for selecting all channels in various frequency ranges.
Algorithm of on-the-fly Subsetting
The core functionality of the HDF-EOS Web-Based Subsetter (HEW), which is developed by the University of Alabama in Huntsville (UAH), has been extracted into a stand-alone callable function known as the HDF-EOS Subsetting Engine (HSE). The AIRS Level-1B and Level-2 subsetter makes use of HSE and can be incorporated into any application that needs to perform HDF-EOS subsetting. The subsetter populates a subsetting criteria data structure which contains the information the HSE needs to operate. This data structure is passed to the HSE which then uses the information to locate and subset the input files into the output files. The output files are then deliver to end user via FTP.
