Direct Broadcast
Aqua AIRS/AMSU/HSB Processing Package for Direct Broadcast
Part of the International MODIS/AIRS Processing Package (IMAPP)
September 22, 2005: Version 4.0 released
The polar-orbiting Aqua spacecraft, launched by NASA in May 2002, provides an X-band direct broadcast service where data from all science instruments is downlinked to the Earth in near real-time. The AIRS/AMSU/HSB Processing Package for Direct Broadcast allows any ground station capable of receiving direct broadcast from Aqua to produce calibrated and geolocated AIRS, AMSU, and HSB Level 1B (calibrated and geolocated instrument observations) and Level 2 (geophysical retrieval) products . This package is functionally identical to the operational AIRS/AMSU/HSB software running at the GSFC DAAC, with the following additions:
a. spacecraft ephemeris and attitude data contained in the X-band downlink may be used for geolocation,
b. overpasses of arbitrary size may be processed,
c. a master control script simplifies the operation of the package.
This package was developed by the AIRS Team at NASA s Jet Propulsion Laboratory. Distribution and support is provided by the Space Science and Engineering Center at the University of Wisconsin-Madison.
