This dataset depicts the Difference for Average Annual Temperature for 2015-2030 and 2045-2060 compared to 1968-1999 for GENMOM.
These data have been generated using a regional climate model called
RegCM3 using boundary conditions from observations or general
circulation models for historical conditions, and from GCM projections
for future conditions.
Regional climate model
description: RegCM3 is the third generation of the Regional Climate
Model originally developed at the National Center for Atmospheric
Research during the late 1980s and early 1990s. Details on current model
components and applications of the model can be found in numerous
publications (e.g., Giorgi et al, 2004a,b, Pal et al, 2007), the ICTP
RegCNET web site (http://users.ictp.it/RegCNET/model.html), and the ICTP
RegCM publications web site
(http://users.ictp.it/~pubregcm/RegCM3/pubs.htm ). The Western North
America domain has a horizontal grid spacing of 15 km and 18 vertical
levels.
RegCM3 requires time-dependent lateral (wind,
temperature, and humidity) and surface [surface pressure and sea surface
temperature (SST)] boundary conditions that are updated every 6 hours
of simulation. Lateral boundary conditions are derived from General
Circulation Model (GCM) output or observations (e.g. NCEP).

These files were created by calculating
differences (anomalies) from the mean 1968-99 climate according to the
given model, and then adding those anomalies to the mean PRISM climate
for 1968-1999
GENMOM is a recently developed GCM that includes
components that have been applied extensively to climate research. The
model is relatively low resolution (T31, ~3.75o x 3.75o) by design, a
compromise that allows long simulations in reasonable time so that the
model can be applied to paleoclimate experiments that commonly are run
for multiple decades and centuries. GENMOM simulations of future climate
were produced under the A2 emission scenario as part of a larger
data-model comparison effort to test the ability of GCMs and RCMs to
simulate North American climate and climatic variability in response to
changes in global boundary conditions (e.g, insolation, atmospheric
composition, continental ice sheets, sea level and paleogeography).
Details and an evaluation of the model to simulate present-day
climatology are given in Alder et al (2011).
