MODIS Direct Broadcast AEROSOL
        Output Product Description
   -------------------------------------------

  The Direct Broadcast aerosol output file differs from the operational MOD04
  output file in that:

  1) It is a 4 byte float binary flat file instead of HDF.  All parameters
     (bands) are of type 4 byte float.  

  2) There are two .img and two .hdr files representing only 6 operational
     MOD04 HDF SDS's listed below.

  3) There are no solar and viewing geometry parameters 
     included as part of the Direct Broadcast product (Latitude / Longitude
     arrays are included).

  4) The output product consists of 14 band interleaved parameters 
     instead of individual HDF file SDS's.  

  5) Only 6 parameters are included.  The 6 are: 
         Latitude
         Longitude
         Optical_Depth_Land_And_Ocean -
            AOT at 0.55 micron for both ocean (best) and land (corrected)
         Optical_Depth_Ratio_Small_Land_And_Ocean -
            Ratio of small mode optical depth at 0.55 micron
         Corrected_Optical_Depth_Land  (3 bands) -
            Corrected optical thickness at 0.47, 0.55, and 0.66 micron
         Effective_Optical_Depth_Average_Ocean (7 bands) -
            AOT at seven bands for average solution at .47, .55, .66,
            .86, 1.2, 1.6 and 2.1 micron

     
  6) There is no quality assurance array or file included with this
     delivery. 

  The MOD04 original direct broadcast release corresponds to the MOD04
  DAAC operational version 4.01.

--------------------------------------------------------------------------
  The aerosol output product consists of a separate
  .img file in flat binary format, and accompanying header file.

  The mod04.img file is a 14 float band interleaved product at 10x10 1km 
  pixel resolution. Please see a list of these bands below.
  The bands correspond to six DAAC Production HDF 
  MOD04 product SDS's. The test output file that you create from the 
  input test data sets contains the nominal MODIS swath size 
  135 (1354/10 elements) and 204 lines (2040 lines/10).  Therefore, the 
  product mod04.img file is 135 elements, by 14 bands (parameters), 
  by 204 lines. In FORTRAN, it would be read as profiles(135,14,204).
  This would be reversed in C - profiles(204,14,135).
