Abstract
We have generated polynomial transmittance coefficients internal to the RTTOV fast radiative transfer model, with atmospheric transmittances calculated by using the FASCOD2 line-by-line model. The FASCOD2 computations are made for a small set of earth representative profiles, uniformly mixed-gases and water vapor molecular species separately and different scanning angles and pressure levels. The accuracy of the process is checked for the NOAA1 1 TOYS channels. A transmittances storage at a medium frequency resolution is tested. This storage allows afterwards any filter convolution of the transmittances and a quick adaptation of the RTTOV model for any new channels.
