Program WNDWDESC

Summary

The wndwdesc program computes corners and write grid description for a Lat-Lon described window ${WNDWNAME} into an I/O API grid ${GRIDNAME}.
Source code for program wndwdesc is available under the GNU GPL License, Version 2, and can be downloaded from the CMAS web site as part of the I/O API distribution tar-ball from this page.

Usage

    setenv  GRIDDESC    <path name for  input file>
    setenv  WNDWDESC    <path name for output file>
    wndwgrid <LAT1> <LON1> <LAT2> <LON2> <GRIDNAME> <WNDWNAME>
    
where

GRIDDESC is the logical name for an existing GRIDDESC-file
WNDWDESC is the logical name for the output GRIDDESC-file
GRIDNAME is the name of a grid in GRIDDESC
(LAT1,LON1) and (LAT2,LON2) are the Lat-Lon coordinates for points in two opposing corners of the requested output grid.
WNDWNAME is the name of the windowed sub-grid of GRIDNAME that encloses (LAT1,LON1) and (LAT2,LON2)
Program wndwdesc will report the corner column and row for the sub-grid of GRIDNAME to the log, after the fashion
SW CORNER (C,R)=        22        27
NE CORNER (C,R)=        66        58
    
and will also write a single-grid GRIDDESC-format file for this windowed sub-grid to the file with logical name WNDWDESC
