在雪，湿裸露的土壤和湖水涡相关测量表明非常小的垂直臭氧通量。需要对小垂直通量进行调整，以考虑到与地面蒸发相关的平均Stefan流的影响以及密度变化和垂直风波动之间的相关性的影响。对于雪，计算的表面的剩余阻力约为34 s cm-1，表明最大沉积速度约为0.03 cm s-1。对于水分饱和的冷裸土，表面阻力约为10 s cm-1（最大沉积速度约为0.1 cm s-1）。获得的最高电阻是转移到密歇根湖的表面，产生的电阻值接近90 s cm-1（0.01 cm s-1的沉积速度）。
Eddy-correlation measurements over snow, wet bare soil, and lake water indicate very small vertical ozone fluxes. Adjustments to the small vertical fluxes are needed to take into account the effect of mean Stefan flow associated with evaporation at the surface and the effects of correlation between density variations and vertical wind fluctuations. For snow, the residual resistance calculated for the surface is about 34 s cm-1, indicating that the maximum deposition velocity is abut 0.03 cm s-1. For cold bare soil well saturated with water, the surface resistance is about 10 s cm-1 (maximum deposition velocity of about 0.1 cm s-1). The highest resistances obtained are for transfer to the surface of Lake Michigan, yielding values near 90 s cm-1 for resistance (0.01 cm s-1 for deposition velocity).
