This file will describe, in brief, the functionality of the FilledMapSubsetter code. The intention of this code is to create an HDF file that contains a defined set of Scientific Data Sets (SDS), whose points are a defined box around an inputted Latitude and Longitude point. The code creates a new file that will contain all of the original file's metadata and SDS metadata. The PERL scripts can handle multiple days and geolocated areas so that processing an entire year of data over multiple areas is simple. In addition, the code allows for a prefix to be attached to the new HDF file for identification purposes (ex. you can name a certain Lat/Lon point ALEXEGT for Alexandria Egypt, such that the new HDF file will be named ALEXEGTMODXY___.hdf). For more detail please see the documentation text files and the summary given at the top of the FilledMapSubsetter.f90 file. This code was written by Eric Moody, Cloud Retrieval Group, NASA GSFC, during April, 2004. Please contact Eric at moody@climate.gsfc.nasa.gov. Thanks.
