Nitrous freeze
WebbThe freezing of the soil surface caused by the low air temperature strengthened the anoxic condition and promoted the production of CH 4, which was emitted when the temperature increased to above zero. Furthermore, freeze-thaw cycles occurring around the second peak had a positive effect on CH 4 emissions. Webb6 mars 2024 · Large fluxes of nitrous oxide occur when frozen soils thaw. Field measurements and mathematical models suggest that freeze–thaw events are responsible for 17 to 28% of nitrous oxide emitted from ...
