Greenhouse gas (GHG) fluxes from soils are highly variable in time and space, and year-round measurements are needed to better characterize emissions from agro-ecosystems, and devise mitigation strategies for emission reduction. Micrometeorological techniques do not interfere with source conditions and hence, can be used quasi-continuously (at hourly to half-hourly intervals) to capture the temporal dynamics of GHG fluxes. My research group is one of the few in the world using micrometeorological techniques for measurement of N2O flux year-round, which has allowed us to characterize the enhanced N2O emissions induced by freeze-thaw cycles. This research is funded by the NSERC-Discovery Grants program.
