README FILE FOR MARS TES PROCESSED DATA

Type of data: Infrared spectra of Mars, observed from above the atmosphere
Instrument: Mars Global Surveyor, Thermal Emission Spectrometer (TES)
Original data source:  These files were extracted from the TES 
                       CD-ROM MGST_0156, which is one of the hundred
                       or so CD-ROM's covering the mission.  
                       Data volumes in the same format to those that
                       have been processed to make the files in this
                       directory can be downloaded from 
                       http://pds-geosciences.wustl.edu/missions/mgs/tes-tsdr.html
                       though the early orbits (including the 0156 volume
                       used here) seem to be not online. 
                       
Processed data:  Each file contans a time series of spectra taken
                 from orbit, looking down at various points on
                 the surface of Mars. There is one spectrum per
                 line.  The files have been subsetted so that they
                 each one contains only data or times when the
                 estimated surface temperature is near a given
                 value (e.g. 220K for TES220.out). This makes
                 the spectra easier to interpret. Each line
                 contains metadata describing the latitude and
                 longitude of the target point,as well as the subsolar
                 latitude and longitude.
                 
                 These files can be read using the script readTES.py,
                 in the Chapter 4 scripts directory
                 
                 This directory also contains wavenumber tables
                 in the files of the form wavenumXX.tab
                 
                 All the files are ASCII text
