PcModWin© is the world standard Windows interface for MODTRAN® (*). The latest version, PcModWin 6, works with MODTRAN6® 6

PcModWin is a commercial Windows version of the United States Air Force Research Laboratory's MODTRAN model. MODTRAN is the recognized standard for computing atmospheric transmission and radiance at medium to high spectral resolution (0.1 cm-1). PcModWin wraps around MODTRAN and makes it easy to use.



 Hitran-PC is a PC computer program that can calculate or model the high-resolution ( < 0.01 cm-1 ) optical transmission spectrum of the atmosphere and of selected gases using primarily the HITRAN Line-by-Line database.   Hitran-PC 4.0, incorporates a major change and advancement in the program and capabilities, and has been developed over the past several years. It now uses the latest 2008 HITRAN Line-by-Line database, but also uses the HITRAN UV and IR Cross Section files, the experimental PNNL IR database, aerosol extinction using the BACKSCAT program, and the water vapor, CO2 and N2 Continuum.
