Subfunction for obtaining climatological values of sill, range, and nugget of spherical variogram model for RAINLINK.

Description

Subfunction for obtaining climatological values of sill, range, and nugget of spherical variogram model. This is based on a climatological variogram based on 30-year automatic rain gauge data sets from The Netherlands. Spherical variograms have been modelled as function of the day number and duration in Van de Beek et al. (2012). They use durations of 1 - 24 h. In this function the relationships can be extrapolated to, e.g. 15-min, data.

Usage

ClimVarParam(DateStr, TimeScaleHours, TimeZone)

Arguments

DateStr	The end date of the chosen daily period.
TimeScaleHours	Rainfall aggregation interval in hours.
TimeZone	Time zone of data (e.g. "UTC").

Value

Data frame with values of sill, range and nugget.
