Abstract:

The MODTRAN atmospheric transmittance and radiance code was upgraded with new band model parameters calculated using the HITRAN-92 line atlas. The 1d band model parameters for O sub 3 were adjusted to give better agreement with the corresponding line-by-line FASCOD3 calculations for long paths in the 20-50 km altitude region. More accurate line-of-sight LOS geometry routines were incorporated for greater consistency between the geometry parameters. Furthermore, MODTRAN can now handle very short slant paths down to 0.001 km.
