==================================================
      SeaDAS 6.4 / 7.0 Processing Update 01      19 Dec 2012
==================================================
This update affects the data processing code distributed with SeaDAS versions
6.4 and 7.0 (beta).

***********************************************************************************************
Important Note for 32bit Linux users - potential GLIBC conflicts:

With this release, the 32bit Linux binaries were compiled on an Ubuntu 12.04
machine, which uses glibc-2.15.  The previous 32bit release was compiled on a
CentOS5.8 machine, using glibc-2.5.  If your system does not have glibc-2.15,
you may need to recompile the binaries locally.

The 64bit binaries were compiled on an Ubuntu 11.04 machine (glibc-2.13).
This has not changed from the previous release.
***********************************************************************************************

Supported platforms for this release are:

- Linux
- Linux x86_64
- Intel Macintosh OS X 10.7 (may work for 10.6 and 10.8 - however not tested)

Added features:

- l2mapgen:
    * geotiff output as float if apply_pal is false
    * outmode modified to accept text as well as integer input
    * exit status modified to allow for proper scripting flow control
- l2gen:
    * default absaer_opt set to -1
    * added PAR support for VIIRS, PIC support for VIIRS and MERIS
    * improved handling of missing values in MODIS/VIIRS
    * updated QAA to version 6
    * VIIRS processing using the OBPG-produced L1A files, see:
        http://oceancolor.gsfc.nasa.gov/WIKI/OCReproc20122VN.html
- modis_GEO.py:
    * added 'entrained' option to allow use of MODIS Packet info even
      if att/eph files can be obtained
- update_luts.py:
    * added support for VIIRS and MODIS xcal files
- modifications to the python scripts to better handle error checking

Bug fixes:

- l2gen:
    * fixed bug with wsmax values < 6.33
    * fixed errors with missing SWIR detectors for MODIS
- smigen:
    * resolved bug with 1km resolution setting
- l2bin:
    * resolved buffer overflow condition
- l2brsgen:
    * resolved buffer overflow condition
- modis_L1A.py:
    * fixed issue with running l0fix on suspect granules
- various and sundry minor bugs eliminated

***********************************************************************************************
                        Installing the update
***********************************************************************************************

Obtain the update tarball appropriate to your system:

Linux (32bit):
seadas_processing_update_linux.tar.gz

Linux (64bit):
seadas_processing_update_linux_64.tar.gz

MacOSX:
seadas_processing_update_macosx_intel.tar.gz

Change directory to your SeaDAS root:
    cd $SEADAS
       or
    cd $OCSSWROOT

Untar the file:
    tar -xzf seadas_processing_update_<arch>.tar.gz

Run the update script:

    cd $OCSSWROOT/updates/update_01/
     ./update_01.sh

***********************************************************************************************
                        Processing Notes
***********************************************************************************************

Prior to running any processing for MODIS or VIIRS, you should update the LUTs
using:

  update_luts.py <sensor>

where <sensor> is aqua, terra, or viirsn as appropriate.

For MODIS, in addition to updating the LUTs, this will modify the file:

   $OCDATAROOT/<sensor>/msl12_defaults.par

to point the xcalfile paramter to the new location under
$OCVARROT/<sensor>/xcal
