Feature: Hydro context Unit conversion #257
Description
Is your feature request related to a problem? Please describe.
Some unit conversions (using xclim) require the context hydro to be able to applied correctly:
See #254 for examples.
This can currently be achieved by specifying a raw_standard_name (for example from https://cfconventions.org/Data/cf-standard-names/current/build/cf-standard-name-table.html) for which the context hydro is automatically inferred.
When making a variable lookup_table this is not so obvious.
Describe the solution you'd like
A more explicit and clear solution would be to add the context: hydro to the variable ID of these variables (either in the specific lookup_yaml or the CORDEX variable list) and use this as context if required.
