etp_pm: Potential evapo-transpiration sensu Penman-Monteith

In achtmalklug/Retp:

Description

Calculates daily potential evapo-transpiration in mm.

Usage

etp_pm(rad, shf = 0, temp = 20, vpd, rh, p = 101.3, r_s = rs(...),
  r_a = ra(...), lh = 2.501 - 0.002361 * temp, ...)

Arguments

rad	net radiation (MJ/(m2*day))
shf	soil heat flux (MJ/(m2*day))
temp	air temperature (dC)
rh	lative air humidity (%)
p	air pressure (kPa)
r_s	canopy surface resistance (s/m)
r_a	canopy aerodynamic resistance in s/m
lh	latent head of vapourisation
vp	air water vapour pressure (kPa)
lai	leaf area index

Value

ra Potential evapo-transpiration in mm/d

Examples

etp_pm(rad=5,shf=0,temp=4,rh=80)
