We have ended up with the current choice of regions because it involves a minimum volume of data that helps the speed of the response. User-specified regions would require much heavier data usage and slow down the prototype.
It would be good to include other data such as reanalysis products and gridded data, which will be a part of the final Copernicus Climate Data Storage. But this is outside the scope of our current project which involves setting up and testing this prototype.
