Investigating the relationship of aerosols with enhanced vegetation index and meteorological parameters over Pakistan

Aerosols have severe effects on climate, human health and ecosystems. The impact of aerosols ecosystems can be better understood if the variability optical properties is accurately known. In this paper, we used Moderate Resolution Imaging Spectroradiometer (MODIS) datasets aerosol depth (AOD) at 550 nm, Angstrom exponent (440/870) (AE) enhanced vegetation index (EVI) over Pakistan. We also analyzed relationship between meteorological variables (e.g., temperature, relative humidity (RH) wind speed (WS)) to acquire a deep knowledge variability. coefficients determination (R2) Aqua-AOD AERONET-AOD are found 0.6724 Lahore 0.7678 Karachi. has been validated with AOD data from Terra, MISR SeaWiFS. High (0.8–1) low AE (0.4–0.8) observed south southwestern Pakistan indicating presence dust aerosols. northeastern Pakistan, EVI negatively correlated AOD. characterized by high values (~1) during all seasons. showed significant interannual variation lowest (0.22) in January highest (0.58) July. lower spring summer than winter autumn seasons south-western A positive R (?0.6) temperature while negative (?0.4 ?)
