摘要：

Global atmospheric transport models are frequently tested by using Rn-222 as a tracer. Generally this tracer is assumed to be emitted at a uniform rate (1 atom cm(-2)s(-1)) from all ice-free land surfaces. The analysis of published data suggests a strong decrease from 30degreesN northwards to 0.2 atom cm(-2)s(-1) at 70degreesN. This could be a result of increasing water tables and proportions of organic soils as indicated by larger proportions of wetlands in northern latitudes.
