Product Description
AIRS Standard OLR and Clear Sky OLR Product
OLR is not directly measured, but is calculated from the retrieved state using a separate rapid algorithm documented in Mehta and Susskind (1999) and NASA Technical Report GSFC/CR-1999-208643. Surface emissivity in spectral regions not measured by AIRS is assumed to be the same as at the nearest spectral point for which an emissivity is obtained. The effective cloud fraction (cloud fraction multiplied by cloud emissivity) is assumed constant throughout the spectrum and is retrieved based on the 11 micron region. Future versions may relax these assumptions.
