Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) gridded annual historical and predicted climate dataEntry ID: EOSWEBSTER_VEMAP2_3
Abstract: The EOS-WEBSTER VEMAP2 Data Collection contains several datasets which provide historical and future climate variables, and monthly and annual biogeochemical model outputs.
Two Tclimate + TScenario Datasets provide annual mean historical and model-predicted climate data from 1895 to 2100 for a subset of the variable available in the monthly dataset. These variables include Tmin, Tmax, ... Precipitation and Solar Radiation.
A dataset is provided for each GCM climate model scenarios:
1) TClimate + TScenario-CGCM1 - historical climate (1895 -
1993) + Canadian Climate Center (see above) predicted future
values (1994 - 2100).
Canadian Climate Center -- Model Name: CCCma -CGCM1;
Experiment: GHG+A 1; 1% per year compounded increase in
equivalent CO2 plus IS92A sulphate aerosols; Ensemble
1.1994-2100. Release: r4.
2) TClimate + TScenario-HadCM2 - historical climate (1895 -
1993) + UKMO/Hadley predicted future values (1994 - 2099)
UKMO/Hadley -- Model Name: HadCM2; Experiment: HadCM2GSa1; 1% per year compounded increase in equivalent CO2 plus IS92A sulphate aerosols; Ensemble 1. 1994 - 2099. Release: r3.
Data provided by the Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) at the National Center for Atmospheric Research (NCAR) are gridded monthly time series climate data for the Conterminous United States at 0.5 x 0.5 degree spatial resolution. Visit the VEMAP2 website for complete information about the VEMAP2 project and datasets.
The VEMAP2 Collection contains the following dataset groups.
1) TClimate - monthly historical climate dataset from 1895 to
1993. Release: r3.
2) TScenario - monthly climate data of possible future values
based on different model scenarios.
3) TClimate + TScenario - annual historical climate data +
possible future values based on the above different model scenarios.
4) TResults - annual biogeography/biogeochemical model estimates
of ecosystem response from 1895 to 2100.

Use Constraints Use of the VEMAP dataset is subject to the following guidelines
(1) Users may confer with the NCAR VEMAP Data Group to ensure
that the intended application of the dataset is consistent
with the generation and limitations of the data.
(2) To help us ... identify dataset errors or inconsistencies, we
request that users contact the NCAR VEMAP Data Group regarding
problems with data files, data access, or the dataset's representation
of climate. For problems with data access or file format, please
refer to http://www.cgd.ucar.edu/vemap/contacts.html
