摘要: Ozonesonde data (11 stations) and Umkehr profiles (13 are analysed for trend detection in the troposphere. All but one of stations located northern hemisphere. The weighted average estimate layer-1 is (0.65±0.69)% per year increase over period 1970–81. free troposphere (850–400mb) detected ozonesonde hemisphere (1.12±0.54)% during past 15 years. These 95% confidence interval estimates. Pronounced seasonal differences revealed from data, with being greatest summer season.
