pet_calc#

Calculate potential evapotranspiration from meteorological inputs.

The module supports several PET methods, mainly temperature-based variants, and handles coordinate metadata, time-step detection, optional parallel processing, and NetCDF output on the original or requested grid.

Functions#

`calculate_pet`(out_file[, tavg_file, ...])	Calculate PET in parallel across time dimension and save to NetCDF.
`e_rad_calculator`(time, lat)	Calculate extraterrestrial radiation (MJ/m²/day) for a given day/lat.
`get_time_and_freq`(ds, stat_freq)	Return time as array and time frequencs as string.
`pet_calculator`(lat, time, stat_freq[, ...])	Calculate PET/ET0 using several formulations (as in your figure).
`validate_tmin_tmax`(tmin, tmax)	Test that tmin smaller or equal tmax at every point and time.
