ET_PenmanMonteith_daily: Penman-Monteith Daily PET

In CCRP-Adaptation/Water-Balance-Reconcilliation: Functions for Calculating Water Balance Variables

Description

Calculates PET (mm) from daily Tmax, Tmin, solar radiation, elevation, and latitude, according to the Penman-Monteith method. May also use daily maximum and minimum relative humidity, atmospheric vapor pressure, and wind speeds.

Usage

ET_PenmanMonteith_daily(x, elev, lat, wind = NULL)

Arguments

x	A daily time series data frame containing Date (date object), tmax_C (deg C), tmin_C (deg C), srad (MJ m^-2 day^-1). Optionally contains RHmax (percent), RHmin (percent), vp (kPa), and wind (m/s).
elev	Elevation of the site (m).
lat	Latitude of the site (degrees).
wind	(optional) An estimated value for daily average wind speeds (m/s). Use if input data frame does not contain daily wind speed values.
