Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) gridded monthly predicted climate data
Entry ID: EOSWEBSTER_VEMAP2_2


Summary
Abstract: The EOS-WEBSTER VEMAP2 Data Collection contains several datasets which provide historical and future climate variables, and monthly and annual biogeochemical model outputs.

The TScenario Dataset provides monthly mean model-predicted climate data from 1895 to 1993. TScenario - monthly climate data of possible future values based on different model scenarios. VEMAP processed these data as follows:

temperature fields - for each month, the modeled change in temperature was added to the 1961-1990 observational baseline.

precipitation fields - for each month the ratio of the modeled change:baseline value was multiplied by the 1961-1990 observational baseline.

radiation and humidity fields - were based on the temperature and precipitation values (from MT-CLIM3) rather than on the actual GCM fields and were not produced as ratios or deltas to the baseline period.

Holdings include the following model scenarios:

1) 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) 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.

Please see the individual dataset group DIFs, for more detailed
information.

Use Constraints
Use of the VEMAP dataset is subject to the following guidelines
and restrictions:

(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

(3) Credit in publications resulting from the use of the VEMAP2
data will be given (a) by citation of VEMAP data set
(http://eos-earthdata.sr.unh.edu/)
and
(b) by acknowledgement of VEMAP sponsors (NASA Earth Science
Enterprise, EPRI, and the USDA Forest Service Global Change
Program) and the VEMAP Data Group (T. Kittel, D. Schimel,
