getCMIP5: Format input parameters

In CIAT-DAPA/analogues: Identification of Climate Analogues

Description

Loads required packages and formats input parameters.

Usage

getCMIP5(var, rcp, model, year, res, lon=NA, lat=NA, path='')

Arguments

var	character: name of variable. Use one of 'prec', 'tmin', 'tmax', 'tmean', or 'bio'
rcp	numeric: representative concentrations pathway (RCP). Use one of 2.6, 4.5, 6.0, or 8.5.
model	numeric: a number from one to 35 indicating the model to be used. The full CMIP5 model list is in cmip5_table. Note that not all models are available for all RCPs.
year	numeric: the future year for which projections are to be downloaded. Available years are 2030, 2050, 2070, and 2080.
res	numeric: spatial resolution, in arc-min. Use one of 0.5, 2.5, 5, or 10.
lon	numeric: longitude (in decimal degrees) of a site so that a tile can be identified. Only needed when res=0.5 data.
lat	numeric: latitude (in decimal degrees) of a site so that a tile can be identified. Only needed when res=0.5 data.
path	character: path where the downloaded files will be stored.

Details

To download 30s precipitation data of a given model, for RCP4.5 in 2030:

getCMIP5(var="prec", rcp=4.5, model=10, year=2030, res=0.5, lon=-75, lat=3, path='')

To download 10min global precipitation data of the same model, for RCP4.5 in 2030:

getCMIP5(var="prec", rcp=4.5, model=10, year=2030, res=10, path='')

Value

A spatial object of class RasterStack with all layers.
