AB: NOAA/NESDIS/ORA has designed, built, and currently operates a near real time data processing and distribution system for the EOS instruments (AIRS, AMSU, and HSB) aboard the AQUA satellite. AIRS, AMSU, and HSB level 0 orbital data packets are received and processed into level 1B (calibrated and navigated) six minute granules. These granules are both spectrally and spatially subset to produce files containing AIRS, AMSU, and HSB brightness temperatures, cloud-cleared radiances, principal components, and principal component reconstructions of radiances. AIRS level 2 temperature and water vapor profiles are generated from the level 1B cloud clear radiances. Data for AMSR-E and MODIS are received from NOAA/NESDIS/OSDPD where it has been processed up through level 1B. AMSR-E level 1B files are received as whole orbits in HDF-EOS format and are converted to BUFR. From the the level 1B, three separate AMSR-E level 2 products are generated for land, water, and atmosphere. MODIS level 1B 1 km observations are collocated to the AIRS footprints and averaged to produce clear and cloudy brightness temperatures, radiances, as well as level 2 products. All the AQUA data products discussed are output in BUFR and over eighty percent are distributed within three hours of observation to meet the operational requirements of NWP centers. Development of a near real time processing/distribution system for the IASI instrument (scheduled to launch on the MetOp 1 satellite in October 2005) is currently ongoing. The design of the EOS AQUA near real time system is providing a design template and useful experience for this and future projects.
