Evapotranspiration (version 1.7)

ReadOBSEvaporations: Read Raw Data of Observed Evaporation from File

Description

Load raw date and evaporation data and then compile data list of daily time step.

Usage

ReadOBSEvaporation(E_OBS, data)

Arguments

E_OBS

A list of evaporation data named "E_OBS" which must contain the following columns: "Year", "Month", "Day" as the date and, "EVAP.Obs" as the observed evaporation in mm. The observations can be of daily and monthly time steps and must match with t

data

A list of data named "data" which contains data of climate variables over the same period as the evaporation data

Value

• This function returns a list with all components of class zoo which have been processed from the raw data, including:
• Date.OBS
  A zoo object containing the date data with time step consistent with the raw evaporation data in "E_OBS".
• E_obs.Daily
  A zoo object containing the daily evaporation data.
• E_obs.Monthly
  A zoo object containing the monthly aggregaated observed evaporation in mm.
• E_obs.Annual
  A zoo object containing the annually aggregated observed evaporation in mm.
• E_obs.MonthlyAve
  A zoo object containing the monthly averaged daily evaporation from observation in mm/day.
• E_obs.AnnualAve
  A zoo object containing the annually average daily evaporation from observation in mm/day.
• Note that the components might have value of NULL when the corresponding raw data cannot be found in "E_OBS".
