Test Data for Functionality Demonstration of HiClimR Package

This data is a subset of University of East Anglia Climatic Research Unit (CRU) TS (timeseries) precipitation dataset version 3.2.

Usage

data(TestCase)

Format

TestCase is a list of three components: x, lon, and lat. x is an (6400 rows by 41 columns) matrix as required for HiClimR function. The rows represent spatial points (or stations), while the columns represent observations (temporal points or years). lon and lat are vectors of length 80 for unique longitudes and latitudes coordinates, where 80 * 80 = 6400 for this gridded data.

Details

CRU TS 3.21 data (1901-2012) is monthly gridded precipitation with 0.5 degree resolution. This test data is a subset with 1 degree resolution for African precipitation in January, 1949-1989.
