release.note

updates on September 25, 2012
- updated the metadata tags to work with the newly released LPGS metadata as well as continuing to support the old metadata tags

updates on January 18, 2012
- fixed bugs in parser program (lndpm.c) while reading metadata file for 
  1) extracting solar zenith angle, 
  2) writing the UTM zone into the ENVI hdr file, and 
  3) dealing with Landsat-4 TM

updates on Septmber 19, 2011
- changes from Eric on the improved processing for the bright surfaces 
- dynamic memory allocation for "lndapp" program so it can handle arbitrary number of columns

updates on January 10, 2011
- changed DEM data from "tbase.bin" (binary) to "CMGDEM.hdf" (HDF format)
- used sea level pressure instead of surface pressure
- updated REANALYSIS ancillary data (using sea level pressure)
- updated ancillary data set up to 2010 

updates on October 15, 2010
- included the internal surface reflectance based cloud mask detection modules 
  (lndsrbm)in this release
- appended thermal brightness temperature (lndth) to surface reflectance file (lndsr)
  using lndapp program
- added DEM_FILE definition in the parser program and included global DEM data 
  "tbase.bin" in ancillary data directory (require downloading new ancillary data)
- updated ancillary data set until September 2010
- removed "MTL" from output filename if it exists 
- moved "bin" directory one level up (same level as src and doc) and revised 
  installation script (env.sh) 
- made "6S" modules (DISCOM.f, OS.f, and INTERP.f) to compatible in g95 compiler 
  (g77 in past), now both 6S modules and lndsrbm cloud mask Fortran code 
  can be compiled in g95 
- added new script "do_ledaps.csh" to run all Ledaps modules automatically like
  do_ledaps.csh <Landsat_Meta_File>
- used actual LMIN, LMAX, QCALMIN and QCALMAX values for ETM+ L1T data (LPGS) 
  if they exist, otherwise still use HIGH/LOW gain settings
