Atmospheric Physics at MISU http://www.misu.su.se/atmphy.htm
The Atmospheric Physics Group's main research is concentrated on improving our understanding of the physics and chemistry that determine the structure and composition of the middle and upper atmosphere.
General Spectral Toolbox http://www.genspect.com/
GENSPECT is a line-by-line radiative transfer code to calculate gas absorption and emissivity, emission and transmission for a wide range of atmospheric gases. GENSPECT has an online web interface is available as a MATLAB toolbox.
NASA Ames Research Center http://geo.arc.nasa.gov/sgp.html
The mission of the Atmospheric Physics Branch (SGP) is to advance the scientific knowledge and understanding of the physical processes that determine the behavior of the atmosphere on earth.
