The license of the data provider (Environment and Climate Change Canada) can be found here https://dd.weather.gc.ca/doc/LICENCE_GENERAL.txt
2) Example Configuration
The example configuration is for the Global Deterministic Prediction System (GDPS) numerical weather system for the TimeseriesImportRun followed by IdMapping and Grid definitions for a wide variety of imports.

3) Instructions for Creating a Subset Grid
To create a smaller grid, follow these steps:
1) Define the bounding box coordinates (https://boundingbox.klokantech.com/, try Dublincore below Copy and Paste for clarity)
2) Fill in the url query below:
https://geo.weather.gc.ca/geomet?SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&COVERAGEID=$VARIABLE_ID$&SUBSETTINGCRS=EPSG:4326&SUBSET=x($westlimit$,$eastlimit$)&SUBSET=y($southlimit$,$northlimit$)&FORMAT=image/netcdf
where:
$VARIABLE_ID$ is from the WCS getCapabilities, or from the externalIDs in this document.
$westlimit$, $eastlimit$, $southlimit$ $northlimit$ are an integer bounding box
3) Paste the query in a webbrowser to download a sample file.
4) In your FEWS application, use the functionaility from the F12 menu --> Clipboard --> Copy grib geometry from file.
5) Paste the grid definition in your grids.xml file
4) Known issues
Subsetting definitions are currently required (original grids cannot be pulled).
