Establishing Validation Sites for Field-Level Emissions Quantification from Grain Sorghum in Southern Great Plains

Exploratory Topics
Stillwater, Oklahoma
Project Term:
10/01/2020 - 06/30/2022

Technology Description:

Oklahoma State University (OSU) will synthesize scientific principles from eddy covariance (a method enabling observation of gas and energy exchange between ecosystems at earth’s surface and the atmosphere), plant and soil science, remote sensing, and crop modeling to measure field-level emissions. The OSU-led team will collect data for field-level emissions of carbon dioxide, nitrous oxide, and methane in grain sorghum production systems in Texas, Oklahoma, and Kansas. Current estimates are from point-based measurements extrapolated using modeling approaches that lack field-scale validation or comprehensive ground truth data. The project’s final deliverable will be gold-standard, publicly-available data sets for quantifying field-level greenhouse gas emissions from grain sorghum production systems.
