SGS-LTER CO2 Elevation Study: Weekly volumetric soil water content, from TDR probes, for Open Top Chamber plots on the Central Plains Experimental Range, Nunn, Colorado, USA 1997-2001

This data package was produced by researchers working on the Shortgrass Steppe
Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University.
Long-term datasets and background information (proposals, reports, photographs, etc.) on the
SGS-LTER project are contained in a comprehensive project collection within the Digital
Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429).
The data table and associated metadata document, which is
generated in Ecological Metadata Language, may be available through other repositories
serving the ecological research community and represent components of the larger SGS-LTER
project collection. Additional information and referenced materials can be found: http://hdl.handle.net/10217/82454. Volumetric soil water content was measured in the 0-15 cm soil depth layer using TDR probes, nearly weekly, in ambient and elevated CO2 open-top-chambers, and unchambered plots. A consistent improvement in SWC was seen in the elevated CO2 plots, while ambient-chambered plots often had lowest SWC. This research was conducted at the Central Plains Experimental Range, near Nunn, CO; lat.40degrees 40 minutes N; long. 104 degrees 45 minutes W in the shortgrass steppe region of NE Colorado, USA and as a collaboration between SGS-LTER and USDA-ARS researchers.
