CDO

Hello all,

I'd like to get the day of the year when a cumulative target temperature is reached, i.e. "get the day of the year when 200°C is accumulated since the beginning of the year".

`timcumsum` is interesting to compute the cumulative sum but I didn't find its equivalent to compute it yearly. I then have to loop over the years to compute my yearly indicator, here is the code I run for the calculation:

for year in years_list:
    year_val = cdo.yearmin(
        input = f"-setctomiss,0 -muldoy -gec,200 -timcumsum -select,year={year} {ifile}", 
        returnArray = 'tas'
    )

I finally concate results for each year to get a single output.

Is there a way to do something similar with CDO, avoiding looping over years?

Thanks,
Pauline
