Water, energy and carbon flux observations from ARS watersheds and agro-ecosystem experimental sites [abstract]. Interagency Conference on Research in the Watersheds. 2011 CDROM. Technical Abstract: Several ARS watershed locations and long term experimental/monitoring sites have been measuring water, energy and carbon fluxes using the eddy covariance technique. Several sites have been collecting flux data for 5 to 10 years, while other locations have recently started a monitoring program. The measurement sites from East to West include corn in Beltsville, Maryland at the OPE3 watershed; pasture and switchgrass fields near State College, Pennsylvania; corn and soybean rotation in the Walnut Creek and South Fork watersheds near Ames Iowa; corn and soybean rotation near St. Paul, Minnesota; grassland near Mandan, North Dakota; grassland and shrubland sites at the Jornada Experimental Range near Las Cruces, New Mexico; riparian, grassland, and shrubland in Walnut Gulch watershed and San Pedro river basin near Tombstone, Arizona; grassland and savanna sites in the Santa Rita Experimental Range near Tucson, Arizona; a riparian site near Reno, Nevada; and, high elevation shrubland and forest sites in Reynolds Creek watershed near Boise, Idaho. This paper provides an overview of the measurements conducted at these sites, and comparisons of energy flux partitioning, water use and net carbon exchange during the growing season. In addition there will be a discussion of possible future multi-location research projects and/or inter-comparison studies involving the eddy flux measurements and ancillary data.
