IIT Madras Links Elevated Aerosols to Thicker Winter Fog Using CALIPSO Data
IIT Madras research, using 15 years of CALIPSO satellite data, links elevated aerosol concentrations with thicker winter fog and larger droplets near the fog top. Aerosols induce vertical mixing through latent heat release, lifting fog tops to about 400–600 m and significantly delaying dissipation. This thickening traps pollutants near the surface, worsening air quality in a feedback loop; reducing aerosol emissions is a key mitigation lever.
