Summary

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

The Tclimate Dataset provides monthly mean historical climate data
from 1895 to 1993. 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://www.eos-webster.sr.unh.edu) and appropriate VEMAP data
papers 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,
A. Royle, N. Rosenbloom, H. Fisher, S. Aulenbach,
and C. Kaufman, NCAR, and C. Daly, Oregon State University) for
access to the data.

(4) The HADCM2 data may only be used for purposes related to
VEMAP or the U. S. National Assessment. For any other purposes, you
must get permission directly from David Viner at LINK
(d.viner@uea.ac.uk).
