Comparison between OSS and "center frequency" methods for modeling of AMSU radiances. The figure shows the RMS between approximate radiances obtained with each model and reference line-by-line calculations.



This plot of the number OSS points required for the NAST-I bands illustrates the enormous savings in computational time over a monochromatic calculation.

OSS was developed with internal R&D funding from AER.  Subsequent support for application and extension of OSS has been optioned from:
