Calculate potential evapotranspiration from temperature

Project description

potEvap

Compute PE (Potential Evapotranspiration) using the formula from Oudin et al. (2005).

This is a pure python implementation of the R - AirGR PEdaily_Oudin function.

Original source found at https://github.com/cran/airGR/blob/master/R/PEdaily_Oudin.R

AirGR package can be found at https://cran.r-project.org/package=airGR

Changes from the original (R package) include:

  • Support single day as well as multiple days (list, numpy array, pandas etc.).
  • Get latitude in degrees or radians (default degrees).
  • Can choose output units (useful for GR2M and GR2A)

Usage:

from from PE_Oudin.PE_Oudin import PE_Oudin

For single value:

temp = 20  # Degrees celcius
date = datetime(2018,1,1)
lat = 32  # Degrees (but can be set to radians)
latUnit = 'deg'  # Optional, and default. Can also be 'rad'
out_units = 'mm/day'  # Optional, and default. Can also be 'mm/month' or 'mm/year'

PE_Oudin.pe_oudin_daily(temp, date, lat, latUnit, out_units)

For multiple values (list, pandas series etc.):

temp = [20, 25] # Degrees celcius
date = [datetime(2018,1,1), datetime(2018,1,1)]
lat = 32 # Degrees (but can be set to radians)
latUnit = 'deg'  # Optional, and default. Can also be 'rad'
out_units = 'mm/day'  # Optional, and default. Can also be 'mm/month' or 'mm/year'

PE_Oudin.pe_oudin_daily(temp, date, lat, latUnit, out_units)
