radfit: Calculate hourly radiation patchiness coefficients

In ilyamaclean/UKCP18adjust: Correct UKCP18 to make it consistent with historic data

Description

Calculate hourly radiation patchiness coefficients

Usage

radfit(sis)

Arguments

sis	an object of class spatial array with hourly radiation values

Details

Using hourlysis(), hourly radiation values are computed by deriving daily optical depths from daily radiation values, interpolating these to hourly and back-calculating radiation for each hour. In so doing, cloud patchiness is under-estimated, leading to potential errors in the calculation of direct and diffuse radiation. The function radfit() derives model coefficients from real hourly radiation data so that spatially and temporally autocorrelated cloud patchiness can be simulated.

Value

a list containing the following components:

m1

A list of semivariagram model coefficients for the six-hourly deviations from daily values

m2

A list of semivariagram model coefficients for the hourly deviations from six-hourly values
