PEdaily_Oudin: Computation of daily series of potential evapotranspiration with Oudin's formula

Description

Function which computes daily PE using the formula from Oudin et al. (2005).

Usage

PEdaily_Oudin(JD, Temp, LatRad, Lat, LatUnit)

Arguments

JD

[numeric] time series of julian day [-]

Temp

[numeric] time series of daily mean air temperature [<U+00B0>C]

LatRad

(deprecated)[numeric] latitude of measurement for the temperature series [rad]. Please use Lat instead

Lat

[numeric] latitude of measurement for the temperature series [radian or degrees]

LatUnit

[character] latitude unit (default = "rad" or "deg")), default = "all"

Value

[numeric] time series of daily potential evapotranspiration [mm/d]
