Paper Abstract

The International MODIS (Moderate Resolution Imaging Spectroradiometer) and AIRS (Atmospheric Infrared Sounder) Processing Package (IMAPP) is supported by NASA with the goals of developing a software package which is freely available for processing MODIS and AIRS/AMSU/HSB Data and promoting and supporting the worldwide use of EOS data, and involving the international community in EOS validation efforts. Both NASA's TERRA and AQUA spacecrafts have direct broadcast (DB) X-band downlinks that allow MODIS (on board both TERRA and AQUA) and AIRS/AMSU/HSB and AMSR-E (on board AQUA only) data to be received in real time by sites having the proper reception hardware. In addition to the current released IMAPP, which allows ground stations capable of receiving EOS direct broadcast data to generate products derived from MODIS and AIRS/AMSU/HSB, products from AMSR-E are under developed. Comparison of one month direct broadcast AMSR-E level 1 data with standard AMSR-E level 2A (level 1 data embedded) data archived by MSFC, NASA, have been carried out and the results have shown that the DB level 1 implementation successfully matches the standard products of brightness temperatures in terms of bias, RMS errors and correlation coefficients, i.e., the DB level 1 data are well calibrated and geo-located and are ready for retrieval for geophysical products. The AMSR-E level 2 products for precipitation and soil moisture are currently under evaluation. Those products will be compared with and validated against the official products.
