Aerosol optical properties and remote sensing

Measuring the whole column of atmosphere above us, and anchoring satellites to the ground

AERONET · PANDORA

How the work is done

Sun photometry for aerosol optical depth and column properties. Spectrometry for column trace gases. Standardised filter sampling and chemical analysis to network protocols, so a sample from Dhaka is directly comparable with one from Addis Ababa or Buenos Aires. Comparison of ground-based retrievals with satellite products over Bangladesh.
