PcLnWin3
version 1.1 (FASCODE)
PcLnWin is Ontar's Windows version
FASCODE. Version 1.1 is based upon the recent
FASCODE3P. PcLnWin calculates the atmospheric
transmittance and radiance using the spectroscopic
parameters obtained in HITRAN. PcLnWin is
the preferred program for all atmospheric
transmission calculations. It includes all
includes aerosols and weather conditions
found in MODTRAN. It is essential when predicting
the performance of high-resolution spectrometers
and laser-based devices (lidars, transmissometers,
and range finders).
The wave number resolution is typically
0.001 cm-1. Although MODTRAN
can be used for low- resolution (broad spectral
response) devices, PcLnWin offers a more
accurate approach. Since its high-resolution
transmission can be degraded to a lower
resolution, it provides a more accurate
spectral transmission than MODTRAN.
