\title{Computation of daily series of potential evapotranspiration with Oudin's formula}


\usage{
PEdaily_Oudin(JD, Temp, LatRad, Lat, LatUnit)
}


\arguments{
\item{JD}{[numeric] time series of julian day [-]}

\item{Temp}{[numeric] time series of daily mean air temperature [°C]}

\item{LatRad}{(deprecated)[numeric] latitude of measurement for the temperature series [rad]. Please use \code{Lat} instead}

\item{Lat}{[numeric] latitude of measurement for the temperature series [radian or degrees]}

\item{LatUnit}{[character] latitude unit (default = \code{"rad"} or \code{"deg"})), default = \code{"all"}}
}


\value{
[numeric] time series of daily potential evapotranspiration [mm/d]
}


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

\examples{
library(airGR)
data(L0123001)
PotEvap <- PEdaily_Oudin(JD = as.POSIXlt(BasinObs$DatesR)$yday, Temp = BasinObs$T,
                         Lat = 0.8, LatUnit = "rad")
