Mandatory Data for the Example 'Climate Normal Grid'

Description

Data needed to demonstrate the working of functions with a grid mode. Average monthly time series of three measured basic climate variables for the normal period 1981-2010 retrieved from the the CarpatClim database (Spinoni et al. 2015), for Csongrád-Csanád County; supplemented with a digital elevation model. Monthly mean relative sunshine duration has been obtained as a ratio of monthly total of sunshine duration and maximum potential number of sunshine hours under clear-sky conditions. Daylength (accumulated hours of daylight) was calculated via Eq 1.6.11 in Duffie and Beckman (1991), according to the SPLASH radiation model (see cliAvgDlySolIrrPoints). For all grids, the WGS84 (EPSG:4326) coordinate system was used with a horizontal resolution of 0.1°.

Format

A list with three RasterBricks and one RasterLayer.

Each of the RasterBricks contains a one-year average monthly time series for the normal period 1981-2010, for the following climate variables:

• temp: mean air temperature (in °C)

• prec: precipitation sum (in mm)

• bsdf: mean relative sunshine duration (dimensionless)

Elevation data can be extracted from a single RasterLayer: elv.
