Projected Monthly Precipitation - 1 km CMIP3/AR4

This set of files includes downscaled projections of monthly total precipitation (in millimeters, no unit conversion necessary) for each month of every year from January 2001 - December 2100 at 1x1 kilometer spatial resolution. Each file represents a single month in a given year. The original SNAP downscaled precipitation product at 2x2 kilometer spatial scale was resampled to a 1x1 kilometer spatial scale using a bilinear interpolation for input in the Integrated Ecosystem Model (IEM).

The spatial extent includes Alaska, the Yukon Territories, and Northern British Columbia.

Scenarios: B1, A1B, A2

Centers, Model Names, Versions, and Acronyms:

Canadian Centre for Climate Modelling and Analysis, General Circulation Model
version 3.1 - t47 (CCMA), cccma cgcm31

Max Planck Institute for Meteorology, European Centre Hamburg Model 5 (ECHAM5), mpi echam5

Downscaling:
These files are bias corrected and downscaled via the delta method using PRISM http://prism.oregonstate.edu/ 1961-1990 (2km Alaska and Western Canada data) as baseline climate. Absolute anomalies are utilized for temperature variables. Proportional anomalies are utilized for precipitation variables.
