**1. [Abstract:]{.underline}** The Cooperative Distributed Interactive
Atmospheric Catalog System (CODIAC) was developed jointly by the Office
of Field Project Support of the [University Corporation for Atmospheric
Research](http://www.ucar.edu/ucar/) (UCAR), the [US Weather Research
Program Office](http://www.oar.noaa.gov/organization/uswrp.html)
(USWRP), the [Forecast Systems Laboratory](http://www.fsl.noaa.gov/)
(FSL), and the National Climatic Data Center (NCDC). Its goal is to
provide researchers with easy access to a distributed meteorological
database held at different data centers.

Within the DSI-6450 dataset is The Global Energy and Water Cycle
Experiment (GEWEX) Continental-Scale International Project (GCIP), fully
implemented in 1995 and phased out in 2001, was launched in the
Mississippi River basin to take advantage of the extensive existing
meteorological and hydrological networks. These networks provide the
best opportunity for obtaining data sets essential to achieving the
overall GCIP goal: To demonstrate skill in predicting changes in water
resources on time scales up to seasonal and annual as an integral part
of the climate system. GEWEX is an integrated program of research,
observation, and science activities ultimately leading to the prediction
of global and regional climate change.

Other datasets included represent various other studies that took place
within the United States and the World. Listed below are the 221 various
datasets contained within DSI-6450, each explaining the contents of the
file, period of record and location. They are listed in alphabetical
order beginning with all caps. More information about this dataset can
be found here at the
[GEWEX/GAPP](http://www.ogp.noaa.gov/mpe/gapp/gcip/) home page. Each
dataset has its own unique element structure and will be more clearly
defined within the data.

**Introduction**

In 1995, the University of Oklahoma's Cooperative Institute for
Mesoscale Meteorological Studies was awarded a research grant by the
Climate and Global change Program of the NOAA Office of Global Programs.
The project was entitled "Meeting GEWEX/GCIP Measurement Needs by Adding
Automated Measurement of Soil Moisture and Temperature Profiles to the
DOE ARM/CART Southern Great Plains Site" (Schneider and Fisher, 1997).
The co-principal investigators, Dr. Jeanne M. Shneider and Dr. Peter J.
Lamb, subcontracted a portion of the work to Oklahoma State University.
Specifically, the subcontractor was responsible for characterizing the
soils and performing independent soil-moisture measurements at each of
the 21 facilities (field research sites) in the ARM/CART study area in
Oklahoma and Kansas.

International Project) Enhanced Observation Period (EOP) Data Set. This
data set contains one table for each of the ARM SWATS (Soil Water
Temperature System) sites at the SGP site containing the fitted values
of the parameters in the van Genuchten and Brooks-Corey equations for

additional quality control was performed by the University Corporation
for Atmospheric research/Joint Office for Science Support (UCAR/JOSS).

This data set consists of data collected by the NOAA/ATDD at their

The objective of this research is to measure and model air-surface
exchange rates of water vapor, sensible heat and CO2 over a temperate
broad-leaved forest and to study the abiotic and biotic factors that
control the fluxes of scalars in this landscape. Scalar flux densities
were measured with tower-mounted measurement systems. Tower-mounted flux
measurement systems were installed above and below a temperature forest
canopy. This configuration allowed us to investigate the relative roles
of vegetation and the forest floor on the net canopy exchange of mass
and energy. We also used the tower-mounted flux measurement system to
study temporal patterns (diurnal/seasonal) of mass and energy exchange
at a point in the landscape.
