【 摘 要 】

Spectrometer MODIS, installed on TERRA and AQUA satellites, provides daily global coverage of the Earth. Based on its measurements, data on aerosol optical depth (AOD) with different spatial resolution are formed: 10, 3, 1 km. The classical algorithm with a coarse spatial resolution of 10 km is not suitable for studying the variability of aerosols at the city scale. Introduced in 2018, a new algorithm for multi-angle implementation of atmospheric correction (MAIAC) provides AOD data with spatial resolution of 1 km. This information can already be used to analyze the spatial distribution of aerosols in the city. The relationship between MAIAC AOD and PM2.5 concentrations of particulate matter was investigated, which is measured at automated posts of city environmental services. Our analysis showed that the data with a spatial resolution of 1 km allow us to see the areas of dust pollution inside the city. This information, together with measurements at the posts, can be used as an objective assessment of the environmental situation.
