Short summary
In this work, the methane emissions from the rice crops of the Ebro Delta were estimated with the Radon Tracer Method, using back trajectories and radon and methane observations. Estimated fluxes show a strong seasonality with maximums in October, corresponding with the period of harvest and straw incorporation. The estimated annual methane emission was about 262.8 kg CH4 ha‑1. Results were compared with fluxes obtained with static chambers showing strong agreement between both methodologies.
