Vegetation-Ecosystem Modeling and Analysis Project

Project Description
The Vegetation/Ecosystem Modeling and Analysis Project, VEMAP,
is 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


1. Comparison of model output for current conditions

2. Intercomparison of the climate and CO2 sensitivity of three
biogeochemistry models (plant production and soil biogeochemical
process models) and three vegetation lifeform distribution
models (biogeography models).

3. Linking vegetation distribution and ecosystem physiology
models to evaluate the joint response of these processes to
altered conditions.

VEMAP is supported by Electric Power Research Institute (EPRI) ,
NASA's Mission to Planet Earth (MTPE) , and USDA Forest Service
Southern Global Change Program. Development of the VEMAP
database was additionally supported by the National Science
Foundation's Climate Dynamics Program through the University
Corporation for Atmospheric Research's Climate System Modeling

The Dataset:

Phase I consists of a database of a model database of climate,
soils, and vegetation compatible with the requirements of three
ecosystem physiology models and three vegetation lifeform
distribution models. The database is on a 0.5 degree
latitude/longitude grid for the conterminous United States.
