Long-term carbon dioxide and water flux database, Walnut Gulch Experimental Watershed, Arizona, USA. Water Resources Research. 44, W05S09, doi: 10.1029/2006/WR05693. Interpretive Summary: The American Geophysical Union has a new thrust to make high-quality data available for research by publishing metadata for a data set that will be available on the web in an AGU-approved web site. This is one of a set of thirteen manuscripts describing data from fifty years of research and data collection at the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) in southeast Arizona, USA. This work describes carbon dioxide and water flux data along with associated meteorological data collected on the WGEW from 1997 through 2006. This report provides background information on the collection and archiving of this data set, and contact information for obtaining copies of the data files. Data and metadata are available via the U.S. Department of Agriculture, Agricultural Research Service, Southwest Watershed Research Center (SWRC) at http://www.tucson.ars.ag.gov/dap/. Technical Abstract: We present the carbon dioxide and water flux data along with associated meteorological data collected by USDA Agricultural Research Service, Southwest Watershed Research Center, on the Walnut Gulch Experimental Watershed (WGEW) from 1997 through 2006. Measurements were collected from a shrub and grass community using the Bowen ratio energy balance systems and presented in 20 minute time steps. Meteorological and Bowen ratio data were imported into spreadsheets for quality control and calculations of carbon dioxide and water fluxes. The data are available at http://www.tucson.ars.ag.gov/dap/ |
