WRFG: Average temperature from WRFG RCM output from NARCCAP

Description

A list containing coordinates and averages of yearly average temperatures from a 24-year period of WRFG-NCEP RCM output on 14606 grid boxes over North America (Weather Research and Forecasting - Grell scheme [WRFG] with boundary conditions provided by the National Center for Environmental Prediciton [NCEP] Regional Climate Model [RCM]).

Usage

WRFG

Format

A list containing five items:

lon

longitude of the grid boxes

lat

latitude of the grid boxes

xc

x coordinates of the grid boxes (Lambert Conformal projection)

yc

y coordinates of the grid boxes (Lambert Conformal projection)

WRFG.NCEP.tas

matrix of average temperatures

Details

RCM output is available through the North American Regional Climate Change Assessment Program (NARCCAP). Data used for this example are from the WRFG model with NCEP boundary conditions. For the years 1981-2004, grid box temperatures (given by the variable 'tas') are averaged over the entire year. Yearly average temperatures for each grid box were then averaged over the 24 year period to create the matrix WRFG.NCEP.tas.
