filter with future mix

Filter with future mix

For meteorological variables, it would be possible to rely on a forecast from NWP. Therefore simulate this by using future values for these variables.

Details

• set future horizon up to which values may be used
• use climatology for further future values (hard break)
• apply mixing procedure (e.g. linear) to soften the transition to climatology

Prepatory work

• write tests for all data handlers to test correct behaviour of own_args, _requirements, and requirements()
• check if all kzf data handlers can be merged with the FIR data handlers -> removed separate KZ data handler
• refac filter classes and introduce tests
• spot all parts of the code, that need to be adjusted to shift the future horizon

important

• it is not allowed to use this feature for chemical variables

(remaining) ToDos

• make plot running again
