Subject: RE: LUT version issues in the DB community
Dear Liam and Phillip,
 
 
There is a directory broadcast package available from
ftp://kratmos.gsfc.nasa.gov/pub/eric/DB
 
called mod09dbv1.0.tar.gz
 
You can gunzip, untar it etc...
 
Once it is done,
 
Please change to the directory called DB_processing
And source the script to set up the environment called sourcethis.first,
By doing:
 
source sourcethis.first
 
You will probably need to update this script depending on how the different libraries and toolkit things are installed on your system.
 
Then, the codes have been compiled for linux on the 32bits machine, they may or may not need to be re-compiled.
 
They are under DB_processing/bin
 
The subdirectories:
 
 MOD09_L2_v5.3.18 for the surface reflectance code
 MOD_PRDS1KM  the 1km destripper
 MOD_PRDS500M the 500m destripper
 
You can rebuild the executable, in each subdirectory (if necessary) by using the provided makefile:
 
MOD_PR09DB.mak for the surface reflectance code
MOD_PRDS1KM.mk for the 1km destripper
MOD_PRDS500M.mk for the 500m destripper
 
Once everything is ready to go, you can run the script on your favorite level 1B data:
The script is directly under DB_processing and is called run_PGE11.csh,
 
Its usage is:
run_PGE11.csh <directory with L1B> <directory with Ancillary data> <date in YYDDD.HHMM>
 
The <directory with L1B> should contains geolocation,level 1B data at the three resolutions (1km,500m,250m)
The <The directory with ancillary data> is ancidata/ if you do not have already an archive
The <date in YYDDD.HHMM> is the date which is part of the file names for L1B and geolocation.
 
Cheers,
Eric
