AM_VIEW calculates AM atmospheric models (see e.g. as parametrized by Guan et al., 2012 (2012A&A...542L...4G). The purpose of this program is to enable users to model atmospheric corrections for astronomical observations in the far-infrared wavelength regime.
The parametrization allows to immediatly calculate model atmospheres for the wavelength range of 60 micron to 200 micron. Input parameters are the predictable water vapour content of the atmosphere [micron], the ambient temperature of the atmosphere [K], the pressure [Torr], the elevation of the observations [deg], the Gaussian spectral resolution (R=λ/Δλ ~ 10-10000) required and the sampling of the output spectra and transmission curves. These can be stored as fitsfiles.

Additionally AM_VIEW indicates the most prominent atmospheric features in this wavelength range (H2O, CO2, O3, N2O, CO, CH4, O2, NO, OH and N2) using the HITRAN database.

Pressure models exist between 75 and 450 Torr in steps of 25 Torr. Intermediate Pressure levels are interpolated linearly.

Additionally, users can implement the two functions that read the am parametrization and calculate the emission/absorption spectrum into their own programs.

AM_VIEW was originally designed for users of the FIFI-LS and GREAT instrument onboard SOFIA.

AM_VIEW needs at least IDL version 7.0.
AM_VIEW runs under LINUX, WINDOWS and MAC.
A minimum screen size of 1024 x 768 pixel is needed.
