ASSIST: Atmospheric Sounder Spectrometer for Infrared Spectral Technology

8 July 2008 - 18 July 2008

Lead Scientist: Michael Howard

Observatory: sgp, sgp

Goals of assist were to intercompare radiance spectra and profile retrievals from a new AERI-like instrument, called "ASSIST" with the SGP site AERI(s) and calculations from Radiosondes measurements.

• To bring the ASSIST instrument to the SGP ACRF and perform simultaneous measurements of the sky radiation with those from the AERI. • On relatively cloud-free days, release a special radiosonde at the MetOp satellite overpass time (1100 - 1200 CDT). • Compare ASSIST radiances with AERI radiances and radiances calculated from the radiosonde observations. Determine systematic and random differences from a statistical ensemble of these intercomparisons. • Perform temperature and moisture profile retrievals from the ASSIST, AERI, and radiosonde calculated radiance observations. Determine systematic and random differences between these retrievals and the radionse observations from a statistical ensemble of these intercomparisons.
