我们从2度x 2度的海洋属性网格计算了海洋损失对一些人为和自然产生的微量气体总寿命的贡献，这些气体与全球变暖和平流层臭氧消耗有关。该模型最初是为大气中的甲基溴开发的，可以用于任何混合良好的痕量气体，其中海水的降解速率常数和溶解度是已知的。在所测试的气体中，很明显，已知的海洋化学降解过程本身并不是大多数氢氟碳化合物和氟氯烃的重要汇。海洋中的化学降解是COS(28%)和COCl2(8%)的主要汇，也是CH3Cl(
We have calculated from a 2degrees x 2degrees grid of oceanic properties the contribution of oceanic loss to the overall lifetimes of a number of anthropogenic and naturally produced trace gases involved in global warming and stratospheric ozone depletion. The model, originally developed for atmospheric methyl bromide, can be used for any well-mixed trace gas where the seawater degradation rate constants and solubilities are known. Of the gases tested, it is clear that known oceanic chemical degradation processes alone are not significant sinks for most HFCs and HCFCs. Chemical degradation in the oceans is a substantial sink for COS (28%) and COCl2 (8%) and a minor sink for CH3Cl (
