Maximum consecutive dry days (CDD): cannot index run length with the last element in the run.

[mer1993]

Description

Hello,

I'm calculating CDD with icclim, and I was looking at the "max_consecutive_occurrence" function in "icclim/src/icclim/_core/generic/functions.py". As far as I understand, icclim uses xclim's "rle" function to calculate the run length, which defaults to the parameter index="first". With this argument, the largest value of the cumulative sum is indexed at the first element in the run (at the beginning of the dry period). However, I would like to use "last" instead, so that the largest value of CDD is reported at the end of the dry spell (the last element in the run), similar to what is done in other packages like Climdex.

However, I can't find a way to pass index="last" as an option in icclim, and it seems that kwargs are ignored in "max_consecutive_occurrence".

Could you please provide guidance on this?

Best regards,
