There are many situations where a user is only interested in a subset of the dataset spatial domain.
For example, when comparing modelled river flow against observations, it is reasonable to being able to extract the timeseries at those point coordinates rather than dealing with many GB of data.
Similarly, when the focus is on a specific catchment it is likely that you want only that part of the spatial domain.
In summary, there two operations that are very popular on CEMS-Flood datasets:
- Area cropping
- Time series extraction
There are different ways to perform those operations:
- From the CDS API (less data is downloaded)
- Locally (full control on the process)
GloFAS Medium-range reforecast (with example area subset)
