  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

  This package is supported by Albert Peter, peter.albert@wew.fu-berlin.de 

  Note: This release consists of the near-infrared water vapor 
        (wvnir) retrieval software.  No other Level 2 product software 
        is 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 near-
        infrared water vapor retrieval product differs from the official
        DAAC MOD05 product.  Please see the modis_wvnir.pdf file for a
        description of the technique.

  WVNIR.tar:   Near-infrared water vapor retrieval source code with
               build and run instructions

               Note: The flatfile extractors must be built
                     prior to the near-infrared water vapor retrieval 
                     source code and both should be built off of the same 
                     core directory, for example /MODIS/wvnir, 
                     /MODIS/flatfile. There is a modis_wvnir.csh 
                     script in the wvnir/src directory which
                     will run the processes together
                     on the test data sets included in the
                     tar file.  As of this release, the flatfile
                     extractors can be found in the IMAPP v1.6 
                     directory.
