RISRelationship of Soil Respiration to Crop and Landscape in the Walnut Creek Watershed
Publisher: American Meteorological Society
Abstract: Soil respiration is an important component of the carbon dynamics of terrestrial ecosystems. Many factors exert controls on soil respiration, including temperature, soil water content, organic matter, soil texture, and ...
Determining Meaningful Differences for SMACEX Eddy Covariance Measurements
Publisher: American Meteorological Society
Abstract: Two eddy covariance instrument comparison studies were conducted before and after the Soil Moisture?Atmosphere Coupling Experiment (SMACEX) field campaign to 1) determine if observations from multiple sensors were equivalent ...
Modeling Evapotranspiration during SMACEX: Comparing Two Approaches for Local- and Regional-Scale Prediction
Publisher: American Meteorological Society
Abstract: The Surface Energy Balance System (SEBS) model was developed to estimate land surface fluxes using remotely sensed data and available meteorology. In this study, a dual assessment of SEBS is performed using two independent, ...
Lidar Measurement of Boundary Layer Evolution to Determine Sensible Heat Fluxes
Publisher: American Meteorological Society
Abstract: The Soil Moisture?Atmosphere Coupling Experiment (SMACEX) was conducted in the Walnut Creek watershed near Ames, Iowa, over the period from 15 June to 11 July 2002. A main focus of SMACEX is the investigation of the ...
Tower and Aircraft Eddy Covariance Measurements of Water Vapor, Energy, and Carbon Dioxide Fluxes during SMACEX
Publisher: American Meteorological Society
Abstract: A network of eddy covariance (EC) and micrometeorological flux (METFLUX) stations over corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] canopies was established as part of the Soil Moisture?Atmosphere Coupling ...
