Seasonal variability of aerosol optical properties and assessment of associated health risks in Pakistan using remote sensing.

Abstract

Aerosols cause a severe impact on the earth’s climate, human health, and ecosystem. By understanding the variability of optical properties of aerosol, the impact of aerosols on the climate, human health, and ecosystem can be known accurately. In this study, we have used datasets of aerosol optical depth (AOD) at 550nm, Angstrom exponent (440/870) (AE) along with soil moisture, natural difference vegetation index (NDVI), and evapotranspiration over Pakistan. To have more in-depth knowledge regarding aerosol variability. We have also analyzed the relationship of aerosol optical properties with temperature, relative humidity, wind speed, soil moisture, evapotranspiration, and precipitation.
