test: Test functions

In metno/esd.test: Climate analysis and empirical-statistical downscaling (ESD) package for monthly and daily data.

Description

This routine contains a series of test functions which compute the global mean 2m-temperature anomalies and other predefined regions based on both CMIP3 and CMIP5 experiments. The main function is test.retrieve.ncdf4. The others are specific cases for the "Scandinavian" and "Arctic" regions for both CMIP3 and CMIP5 projects

Usage

test.retrieve.ncdf4(path="CMIP3.monthly/20c3m-sresa1b",param="auto",cntr= "Global",
                    lon=NULL,lat=NULL,time=NULL,lev=NULL,experiment="CMIP3",
                    climatology=c(1986,2005),fig=TRUE,saveinfile=TRUE,verbose=FALSE)

test.cmip3.arctic(...)
test.cmip5.arctic(...)
test.cmip3.global(...)
test.cmip5.global(...)
test.cmip3.scandinavia(...)
test.cmip5.scandinavia

test.cmip35.global()

Arguments

path	Character vector of the path to the CMIP data.
param	Parameter or element type. There are several core parameters or elements as well as a number of additional parameters. The parameters or elements are #(Abdelkader : We need to update this list): auto = automatic selection. prcp, pr = Precipitation (mm) tas, tavg = 2m-surface temperature (in degrees Celcius) tmax, tasmax = Maximum temperature (in degrees Celcius) tmin, tasmin = Minimum temperature (in degrees Celcius)
lon	Numeric value of longitude for the reference point (in decimal degrees East) or a vector containing the range of longitude values in the form of c(lon.min,lon.max)
lat	Numeric value of latitude for the reference point (in decimal degrees North) or a vector containing the range of latitude values in the form of c(lat.min,lat.max)
lev	Numeric value of pressure levels or a vector containing the range of pressure level values in the form of c(lev.min,lev.max)
time	Numerical year values or date values of time or a vector containing the range of values in the form of c(time.min,time.max). Date format should be in the form of "YYYY-MM-DD".
saveinfile	Logical or a character value. The output filename is set automatically if not specified. Default value is "TRUE".
verbose	Logical value. If TRUE, do not display comments (silent mode)
