Suppose that you are provided with two items, a mapping file describing your study site of interest and a zipped folder of files that you will need to use. The mapping file describes the gridded cell centroids for each 1/16th longitude-latitude gridded cell within the study site, and the files within the folder follow the same gridded cell centroid schema in their naming conventions. The folder may contain more files than is necessary, so the mapping file will need to be used to isolate the files of interest after they have been unzipped.

These two files are intended as a tutorial materials. The Observatory for Gridded Hydrometeorology (OGH) python library contains a function called 'remapCatalog', which will be used to construct a new column in the mapping file. The column will be filled with the file path for the files that correspond to each gridded cell centroid. Files that are missing will be filled with NA.
