Soil Moisture and Surface Flux Variability at the Kessler Atmospheric and Ecological Field Station

Measuring carbon dioxide, methane, and water vapor fluxes between the land surface and the boundary layer using the eddy covariance method has many applications. During 2016 and 2017, an integrated grassland observing system (IGOS) site correlation was installed at the 400 acre Kessler Atmospheric and Ecological Field Station (KAEFS) near Purcell, Oklahoma. The IGOS site includes a flux tower which is equipped with an eddy covariance system, a COSMOS, and in-situ observations of atmospheric variables and soil moisture. In addition, KAEFS hosts the Washington, Oklahoma Mesonet station (approximately 115 meters away) which collects in-situ observations of atmospheric variables and soil moisture. This project completed an initial analysis of the in situ observations with a focus on the temporal variability at the site.
