The LSM's atmospheric library is made up of an extensive set of integrated atmospheric data bases created by the Atmospheric Generator Model (AGM). The library can provide meteorological inputs from control fields, generated fields, mesoscale fields to global meteorological fields. The library also includes aerosol backscatter, molecular and aerosol attenuation, atmospheric turbulence and terrain. 

GLOBAL ATMOSPHERIC DATA SET (GADS)

The Atmosphere Generator Model (AGM) creates Global Atmospheric Data Sets (GADS) that the LSM uses for global type simulations. A GADS is a FORTRAN 90 direct access file created by using a "Nature Run" data set in liaison with the AGM optical property models and terrain data set.  The LSM retrieves atmospheric profiles as a function of latitude and longitude for each laser shot and linearly interpolates in time and space to estimate the atmospheric variables for each 4D lidar location. 

The MLSM version 1.0 has one day of a Mars GADS in the atmospheric file inventory. The AGM used a Global Climate Model (GCM) database (Laboratoire de Météorologie Dynamique du CNRS, France) for the "Nature Run" candidate in making the GADS.
