NARCCAP CRCM-CCSM tasmax 2041-2069
Description
This archive consists of two data sets stored in the compressed format of R Statistical Software. The first data set, tasmax.rda, is an array of dimension 140x115x10585. The data are maximum daily surface air temperature (K) output from the Canadian Regional Climate Model (Caya and Laprise, 1999) combined with the the Community Climate System Model global climate model (Collins et al., 2006). The data are simulated temperature for the time period 2041-2069 and were produced as part of the North American Regional Climate Change Assessment Program (NARCCAP, Mearns et al., 2009). Each slice of the array along the 3rd dimension represents the temperatures for a specific day, starting with January 1, 2041 and running through December 31, 2069. e.g., tasmax[,,1] is a 140x115 matrix of temperatures for January 1, 2041. All years are assumed to have 365 days. The second data set, crcm_covar.rda, contains the longitude, latitude, and elevation (m) of the grid cells as 140x115 matrices. References: Mearns, L. et al.
