Calculates missing values of relative humidity, radiation and potential evapotranspiration from a data frame with daily values of minimum/maximum/mean temperature and precipitation. The function takes a meteo object (with meteoland names) and complete any missing variable if it is possible
Usage
complete_meteo(meteo, verbose = getOption("meteoland_verbosity", TRUE))Details
#' The function fills values for humidity, radiation and PET only if they are missing in the input data frame. If a column 'SpecificHumidity' is present in the input data, relative humidity is calculated from it. Otherwise, relative humidity is calculated assuming that dew point temperature equals the minimum temperature. Potential solar radiation is calculated from latitude, slope and aspect. Incoming solar radiation is then corrected following Thornton & Running (1999) and potential evapotranspiration following Penman (1948).
