A simulation of long-range transport of CFCS in the troposphere using a 3-D global lagrangian modle with 6-hourly meteorologicla fields

摘要

Throughout this century the composition f the troposphere has been perturbed by antheorpogrenic emissions.These emissions are not uniformlay distriubted obver the globe but are ocncentrated in the northern mid-latitudes in industrial regions.Biogenic emissions are largely emitted form the land and os toto are biased towards the northern hemisphere.A modelling study of the global chemistry of the troposphere requres knowledge of how pollutants are carried away from their mainly cntinental source regions to the remote atmosphere and the southern hemisphere.
