Research Project: Automated Measurements of Greenhouse Gas Emissions from Soils with Radar-Based Estimates of Soil Moisture in Agriculture & Forest Ecosystems

Location: Northern Great Plains Research Laboratory

Project Number: 3064-21660-003-08
Project Type: Reimbursable

Start Date: Feb 15, 2011
End Date: Feb 28, 2015

Quantify differences in measurement methods by comparing manual with automated chamber techniques using new Quantum Cascade Lasers (QCL) and Wavelength-Scanned Cavity Ring Down Spectroscopy (WS-CRDS) for wetland/cropland/rangeland mixed-use agricultural ecosystems.

We will set up arrays of probes in mixed-use agricultural sites to continuously and manually monitor gas fluxes, soil moisture and soil temperature. Manual measurements will be collected weekly and compared with automated data collection chambers.
