  This directory contains tarfiles of the International MODIS
  and AIRS Processing Package (IMAPP) Products.  The software is 
  supported on the following platforms: 

   (1) SGI, IRIX64 6.5

   (2) SUN, SunOS 5.7, sun4u sparc SUNW,Ultra-5_10

   (3) IBM, AIX 4.3

   (4) LINUX, 2.4.7-10smp, compiled with g77/gcc.

   (5) HP,  HP-UX, B.10.20

  Note: This release consists of the sea surface temperature software.
        No other Level 2 products are included in this release,
        nor do they need to be updated prior to using this software.

        Note: The technique used in the creation of the IMAPP sea
        surface temperature product differs from the official
        DAAC MOD28 product.  Please see the SST_DOC.pdf file for more
        details.

  SST.tar:     Sea surface temperature source code with
               build and run instructions

               Note: The flatfile extractors must be built
                     prior to the sea surface temperature source 
                     and both should be built off of the same 
                     core directory, for example /MODIS/sst, 
                     /MODIS/flatfile. There is a modis_sst.csh 
                     script in the sst/src directory which
                     will run the processes together
                     on the test data sets included in the
                     tar file.
