Description
Function to clean the ESR data (necessary before running Christian et al. method)
Usage
1
Christian_clean_data_week(vtime, vET0, vETa, threshold = 1)
Arguments
vtime
data frame column or vector containing date data
vET0
data frame column or vector containing daily potential evapotranspiration (mm.day-1)
vETa
data frame column or vector containing daily actual evapotranspiration (mm.day-1)
threshold
a positive number, indicates the maximum ratio ETa/ET0 allowed.
Details
Due to data and modelling quality, eventualy ETa >> ET0, causing errors, particularly in cold days when ET0 ≈ 0.
This function allows the reduction o distortions. Pentads discarded are interpolated.
Value
It returns a list with two elements. A data frame with time stamps and pentad ESR and a matrix with ESR data distributed in a 73 lines (pentads).
Examples

3
Christian2020_clean_data(vtime = df_d$time,
vET0 = ET0$et0, vETa = ETa$eta,
threshold = 1)
