提出了数百种对草地、土壤、沙子、淡水、海水和雪的表面臭氧吸收阻力的新测量。与之前的研究结果一致，草地和土壤的日间表面阻力中值为100 sm−1。第一个直接证据表明，草地和土壤的表面阻力在夜间增加，夜间的表面阻力值约为300 sm−1。海水和雪的表面阻力相当大，约为1000至2000 sm−1。利用上述资料和其他已公布的臭氧数据，得出了地球表面具有代表性的全球臭氧破坏率。考虑了不同类型地表的纬向变化及其不同的臭氧破坏常数、地表空气中臭氧的纬向和日变化以及近地表涡旋输送的日变化。据估计，全球平均臭氧破坏率在2至6 × 1029分子s−1（0.5至1.5 × 1012kg yr−1）之间。这个范围比以前的估计值略高。南半球和北半球的臭氧破坏率之比约为2:3。讨论了对对流层臭氧循环的影响。
Several hundred new measurements of the surface resistance to ozone uptake of grass, soil, sand, fresh water, sea water and snow are presented. Grass and soil show, in agreement with previous work, a daytime surface resistance of median value 100 sm−1. The first direct evidence is presented of a nocturnal increase in surface resistance for grass and soil, with night‐time values of surface resistance of about 300 sm−1. The surface resistances of sea water and snow are considerably larger, about 1000 to 2000 sm−1. A representative global ozone destruction rate for the earth's surface is derived using the above information and other published ozone data. Allowance is made for the latitudinal variation of the different types of surface, their various ozone destruction constants, the latitudinal and diurnal variation of ozone in the surface air and the diurnal variation of eddy transfer near the earth's surface. The global average ozone destruction rate is estimated to be in the range 2 to 6 × 1029molecules s−1(0.5 to 1.5 × 1012kg yr−1). This range extends to slightly higher values than previous estimates. The ratio of ozone destruction rate between the southern and northern hemispheres is about 2:3. The implications for the tropospheric ozone cycle are discussed.
