Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) gridded annual and monthly biogeographic and biogeochemical time series data

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

The TResults Dataset group contains 4 individual datasets, which
include two differerent GCM Climate prediction model inputs and two
different CO2 scenarios. Holdings in these four datasets include
annual and monthly biogeography/biogeochemical model estimates of
ecosystem response from 1895 to 2100. Six different ecosystem process
models are represented in the holdings.

The two different GCM models used for climate inputs to the ecosystem
process models are:

1) Canadian Climate Center -- CGCM1 scenario:
constant CO2 (1895 level; 294.842 ppm); 1895-2100
increasing CO2 (IS92a global yearly dataset); 1895-2100

2) UKMO/Hadley Center -- HadCM2 scenario:
constant CO2 (1895 level; 294.842 ppm); 1895-2099
increasing CO2 (IS92a global yearly dataset); 1895-2099

The Following Biogeochemical Variables are predicted by the six
ecosystem models:

1) Net Primary Production (NPP): Annual & Monthly data
2) Actual Evapotranspiration (AET): Annual & Monthly data
3) Net Ecosystem Productivity (NEP): Monthly data
4) Net Nitrogen Mineralization (NNM): Annual data
5) Total Carbon Storage (TCS): Annual data
6) Total Vegetation Carbon (TVC): Annual data
7) Leaf Area Index (LAI): Monthly data

The following six biogeochemical models are represented in the
holdings, and the associated predicted variables:

1) Biome-BGC: TVC,AET,NPP(annual only),NNM,TCS
2) Century: TVC,AET,LAI,NEP,NPP,NNM,TCS
3) LPJ: TVC,AET,NPP,TCS
4) MC1: TVC,AET,NEP,NPP,NNM,TCS
5) TEM: TVC,AET,NEP,NPP,NNM,TCS
6) GTEC: AET,NEP,NPP(monthly only),

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 and monthly biogeography/biogeochemical model estimates
of ecosystem response from 1895 to 2100.
