Distribution and hotspot detection of NO2 column concentration in Henan province in 2022
摘要
Abstract
Based on Sentinel-5p satellite imagery data,this study analyzes the spatial and temporal distribution of annual and monthly average NO2 column concentration in Henan Province in 2022.The fast-decay inverse distance hotspot analysis method is applied to identify NO2 hotspot areas.The results show that NO2 column concentration in Henan Province exhibits high concentration in winter and spring but low in summer,with a U-shaped temporal symmetry.Spatially,NO2 column concentration exhibit higher concentration in the northeast and lower in the southwest,with high values concentrated mainly in the urban districts of Anyang,Hebi,Xinxiang,and Zhengzhou along the Taihang Mountains.The fast-decay inverse distance hotspot analysis method effectively detects NO2 hots-pot areas across multiple scales,facilitating further investigation and verifying of NO2 emission sources.关键词
