Model Overview

ModelVEMAP 2: Monthly Historical and Future Climate Data, Alaska, USA
Release date2016-10-17
ProjectVegetation-Ecosystem Modeling & Analysis Project (VEMAP)
Time Period1922-01-01 to 2100-12-31


This data set provides the results of the development of The Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) Phase 2 transient climate change scenarios for the state of Alaska, USA. The data include gridded monthly historical and future estimates of maximum and minimum temperature, solar radiation, vapor pressure, irradiance, relative humidity and potential evapotranspiration at 0.5-degree spatial resolution. Historical data are for the period 1922-1996; future estimates cover the period 1997-2100.

Vegetation-Ecosystem Modeling & Analysis Project (VEMAP): A multi-institutional, international effort whose goal is to evaluate the sensitivity of terrestrial ecosystem and vegetation processes to altered climate forcing and elevated atmospheric CO2. Phase 1 of the VEMAP project developed a model database of climate, soils, and vegetation compatible with the requirements of three ecosystem physiology models and three vegetation lifeform distribution models. Phase 2 developed a historical (1895-1994) gridded data set of climate (temperature, precipitation, solar radiation, humidity, and wind speed) and transient climate change scenarios based on coupled atmosphere-ocean GCM experiments, such as those with elevated greenhouse gases and sulfate aerosols.
