The .grd files are a type of netCDF file built within the GMT environment and hold all the strain rate values
for each epoch of time for each given grid type. These can be used within GMT (https://docs.generic-mapping-tools.org/latest/),
as well as other software types (e.g., GDAL, MATLAB).

YYYYMMDD indicates end date of the weekly grid
