Solar radiation data derived from air temperature differences

If global radiation is not measure at station, it can be estimated with this function.

Usage

sr_tair_calculation(latitude, date, tmax, tmin, location_krs)

Arguments

latitude

A dataframe with latitude in decimal degrees that you want to calculate the ra.

date

A dataframe with the dates that you want to calculate the ra.

tmax

A dataframe with Maximum daily air temperature (Celsius)

tmin

A dataframe with Minimum daily air temperature (Celsius)

location_krs

Adjustment coefficient based in location. Please decide between "coastal or "interior". If coastal the krs will be 0.19, if interior the krs will be 0.16.

Value

A data.frame object with solar radiation data
