► Aerobic rice fields had 45% more sensible heat flux than flooded fields while flooded rice fields had 19% more latent heat flux than aerobic fields. ► Bowen ratio of aerobic field (0.24 ± 0.01) was higher than flooded field (0.14 ± 0.03). ► Aerobic field had lower average growing season ET rate (3...
