通过穿透雨和涡动相关方法测量森林中直径为0.1 ~ 1.0 μm的颗粒干沉降，结果为1.0 cm s-1或更大，而机制模型不能解释大于1 mm s-1的值。还回顾了其他放射性示踪方法的结果。这些数据表明值约为5 mm s-1。从模型中省略的额外机制的可能性很难排除，但剩余的差异大部分可能是由于大气中外来放射性示踪剂的广泛尺寸分布。
Measurements of dry deposition ofparticles 0.1 to 1.0 μm diameter to forest bythroughfall and eddy correlation methods giveresults of 1.0 cm s-1 or more, whilemechanistic models do not explain values greaterthan about 1 mm s-1. Results of othermethods involving radioactive tracers arerecalled. These data indicate values of about 5 mm s-1. The possibility of additionalmechanisms, omitted from the models, is difficultto exclude, but much of the remaining discrepancymay be due to the wide size distribution of theadventitious radioactive tracers in the atmosphere.
