The Eddy Covariance Method

The Eddy Covariance Method

IRRI’s climate change research covers various aspects of adaptation and mitigation in rice production systems. Mitigation research focuses on developing technologies and crop management practices that can reduce methane (CH4, a potent greenhouse gas) emissions, and increase the carbon (C) sequestration in biomass and soil to reduce the carbon footprint of irrigated rice.

The eddy covariance (EC) system is an effective tool that IRRI uses in ensuring that the mitigation and adaptation options that the institute develops to minimize the impacts of climate change on rice production have also minimal environmental footprints. It is widely employed as the standard micrometeorological method that directly measures carbon dioxide (CO2), CH4, water vapor, and heat fluxes over a large area. On the minimum, the EC can cover a 100-m radius, which corresponds to a field size of 4 hectares.
