Analysis on the Spatial-temporal Distribution Characteristics of O3 over Sichuan Province
摘要
Abstract
Spatial-temporal distribution and variation characteristics of O3 in Sichuan in 2005 ～ 2015 was analyzed using OMITO3 e total Ozone Products.Results showed that:1.Spatially,the cumulative value of O3 in the past 11 years was high in the north and East,and low along the south and the west.The annual mean O3 of prefecture-level cities in the high-value region is mainly distributed in the central Sichuan Basin city group and in the northern Sichuan taking Guangyuan,Bazhong,Nanchong,Dazhou as the core.The annual mean O3 in the low-value region is mainly distributed in the Ganzi Tibetan Autonomous Prefecture and Liangshan Yi Autonomous Prefecture and Panzhihua region.2.Temporally,the O3 from 2006 to 2009 showed a declining trend,and the increasing amplitude in 2015 is obvious.Also the average O3 is high in spring and summer,and low in autumn and winter.The monthly mean O3 is high in April,and low in October.3.The temporal and spatial distribution of O3 over the Sichuan is affected by solar radiation,terrain,cloud fraction,source and other factors.关键词
