Satellite project Aerosol-UA for polarimetric remote sensing of aerosols in the terrestrial atmosphere

Why aerosols?

According the Radiative forcing concept (© IPCC, Stocker et al. 2013), aerosols in the terrestrial atmosphere is most variable by space and time constitution that impacts on the energy balance.

1. Aerosol impact as the component of radiative forcing has largest uncertainty to estimate.

That is the result of the target choice for the space mission Aerosol-UA


Direct and indirect impact of aerosol on climate system (clouds-albedo) © 2013 Nature Education

Highest effect with absorbing aerosol (black carbon) above black, dark surface (warming effect)



Aerosols fine fraction particles contribute to the formation of more powerful clouds with a longer life (cooling effect)
