Parameters:

INFILE
Input file. A file containing the daily observation values of TOVS water vapor.

OUTDIR(--)
Output directory. The directory in which the output image will be created. If left as NULL (--) the current directory will be used.

Examples:

  1. LAS> tovsin infile="tovsb990101e990131amnj;bin"

    Thirtyone single-band LAS images will be created from the input file. The output images will be named wv1401xx99am where xx will range from 01 to 31.

The input file will be converted to a binary file. This binary file is translated to a LAS image and the DDR edited to put the image in geometric projection with the proper corner coordinates. The new LAS image is renamed to the TOVS water vapor file format and placed in OUTDIR or left in the current directory.
