The displacement grids and auxiliary files (vector, residuals, transients, movies) are created from the Level 2 daily displacement time series. They are 
described in the Chapter 5 tables of our ATBD document.

Note: Files with a W in their title indicate a weekly product, while files without W in their titles indicate a product that is cumulative over time.

The .grd files are a type of netCDF file built within the GMT environment and hold all the displacement data values
for each epoch of time for each given grid type. These can be used within GMT (https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.generic-2Dmapping-2Dtools.org_latest_&d=DwIFAg&c=-35OiAkTchMrZOngvJPOeA&r=wsdZDTPjLionAqWs_WzfpA&m=vyd_MKsy3dmR_9KXNJJX97HBVSO_A8cmUb6dIg6p_HE&s=P9hM9rPyZvouimXZUtDbL5gRZZZBD2umWE82X408Qcs&e= ),
as well as other software types (e.g., GDAL, MATLAB).

YYYYMMDD indicates end date of the weekly grid
