Research of Aerosol Optical Depth and Urban Heart Island in Lanzhou City by Means of Earth Remote Sensing
This chapter contains an analysis of the aerosol optical depth (AOD) and the urban heat island (UHI) basing on the images obtained from the Landsat and MODIS satellite (Terra/Aqua), using software ENVI5.1 and ArcGis10.2 and using an algorithm of the land surface temperature (LST) and normalized difference vegetation index (NDVI), to determine the urban heat island effect and the atmospheric pollution, to estimate the environmental situation in the city of Lanzhou completely, and to perform analysis and forecasting models of aerosol according to the NAAPS (Navy Aerosol Analysis and Prediction System), as well as to determine the characteristics of the vertical distribution of aerosols and dust using CALIPSO.
