Announcement: MODISL1DB 1.4 Released

MODISL1DB 1.4 is now available for the MODIS DB community via http://oceancolor.gsfc.nasa.gov/seadas/modisl1db/. MODISL1DB is a MODIS Level-1 Direct Broadcast software package capable of processing Aqua and Terra Level-0 data to Level-1A and Level-1B.

In this update, the modis_l1agen (MOD_PR01) and geolocate (MOD_PR03) binaries have been updated to be in sync with the latest MODIS Science Data Support Team (SDST) code. These changes were predicted to have little effect on the data and initial tests performed by the OBPG support this.

If you have already installed a previous version of MODISL1DB, simply install MODISL1DB 1.4 in a new directory and point your DBHOME environment variable to this new directory. If you already have the digital elevation maps, there is no need to re-download them. You can simply move them into the new $DBHOME/data/modis/dem/ directory or create a symbolic link that points to them.

-Best regards from the Ocean Biology Processing Group!-

MODISL1DB 1.4 CHANGES
=====================

Supported platforms:

CentOS 4.4
Fedora Core 6
Fedora Core 4
Fedora Core 2
RedHat 7.3
Macintosh OS X 10.4 Intel
Macintosh OS X 10.3/10.4 PowerPC
Solaris 2.8 (64-bit binaries only)

=====================
Level 0 to Level 1A processing changes:

-new modis_l1agen binary (MOD_PR01 V5.0.3): code updated to be in  sync with the latest SDST code

-updated Aqua/Terra geolocation maneuver, geolocation parameter, and ENG_DATA_LIST files to V5.0.27

-fix_L0 binary: fixed a small counting error

-date2jd binary: fixed bug on certain linux systems that would result in the error "set: Variable name must begin with a letter"

-updated modis_L0_to_L1A_GEO.csh script:

  -added the "-n next_granule_filename" option for specifying the next
   concurrent L0 granule. This enables geolocation of the last scanline
   of the input L0 file. Setting this option forces the stopnudge
   parameter to be set to 0.

  -added the "-b" option to activate use  of the base of the input
   filename up to first "." for output filenames. This is so filename
   bases can now be kept identical through the processing chain instead
   of the seconds potentially changing...
   e.g.: A2007111165000.L1A_LAC -> A2007111165001.GEO

  -fixed some "rm" statements to use "rm -f" for users who's environment
   has a "rm -i" alias set.

=====================
Geolocation processing:

-new geolocate binary (MOD_PR03 V5.0.6): code updated to be in sync with the latest SDST code

-updated Aqua/Terra geolocation maneuver, geolocation parameter, and ENG_DATA_LIST files to V5.0.27

-Extraction metadata from the L1A file (if present) is now copied to the geolocation file, e.g.:
       Extract_Pixel_Offset = 396
       Extract_Pixel_Count = 226
       Extract_Line_Offset = 258
       Extract_Line_Count = 36

This can be accessed by the user and is also detected by the SeaDAS msl12 and msscanpixlimits binaries.

-updated modis_L1A_to_GEO.csh script:

  -added the "-b" option to activate use  of the base of the input
   filename up to first "." for output filenames. This is so filename
   bases can now be kept identical through the processing chain instead
   of the seconds potentially changing...
   e.g.: A2007111165000.L1A_LAC -> A2007111165001.GEO

-updated modis_definitive_atteph.csh script:

  -the definitive attitude files have been changed from AM1ATTNF.A* to
   AM1ATTN0.A*. This is spacecraft attitude that has been refined by the
   Level 0 processing facility. AM1ATTNF.A* files are the FDD (Flight
   Dynamics Division) predicted data from flight dynamics. According to
   MODAPS, they are used only for spacecraft-manuever periods, where
   typically the ATTN0 files will be absent or not work.

=====================
Level 1A to Level 1B processing:

-modis_L1A_to_L1B.csh:

  -added the "-b" option to activate use  of the base of the input
   filename up to first "." for output filenames. This is so filename
   bases can now be kept identical through the processing chain instead
   of the seconds potentially changing...
   e.g.: A2007111165000.L1A_LAC -> A2007111165001.L1B

=====================
-improved modisl1db_benchmarks.bash benchmark script to report both CPU time and wall clock time

=====================
-fixed bug in modis_update_luts.csh script so it no longer fails when no calibration LUTs whatsoever exist on a user's hard disk
