Characteristics and Correlation of Land Surface Temperature and Aerosol Optical Depth in Urumqi
Urban temperature rise and air pollution will have a huge impact on human production and life.The correlation between surface temperature and aerosol optical depth in Urumqi was studied by using multi-source remote sensing data and GIS technology.The results show that ① The monthly mean daytime land surface tem-perature in Urumqi was the highest in July and the lowest in December;the land surface temperature is highest in summer and lowest in winter.During the annual change,the surface temperature increased from 2010 to 2020 as a whole.② The monthly mean aerosol optical depth in Urumqi is larger in February and April,and smaller in No-vember and January.The average annual temperature increased in 2010,2015 and 2020.The annual mean changes is similar to the surface temperature.③ There was significant positive correlation between surface temperature and aerosol optical depth in monthly,seasonal and annual.This study can be used as a reference for urban envi-ronmental pollution control in Urumqi.
