recipe_globwat.yml takes more than 12 hours to run

[schlunma]

Describe the bug
recipe_globwat.yml didn't finish in a 12 hour-period (https://esmvaltool.dkrz.de/shared/esmvaltool/v2.5.0-test-rc2/recipe_globwat_20220213_145613/run/main_log_debug.txt). The reason for this is that it regrids the 30 years of daily data to a 2160x4320° grid (given by a target grid stored in our auxiliary data directory). After that it does a calculation for each of the 11323 days which takes about 30s for each individual day. --> Estimated run time > 90 hours (!).

I'm wondering if it's possible to reduce the time period of the data (we can leave the original time period in a comment). I tested the recipes with 30 days and just runs fine.

@SarahAlidoost I saw that you are an author of this recipe, what is your opinion?

Thanks, I think using the smaller time range should be fine too.
