Kinne, S., Quaas, J., (2004). Aerosol Radiative Forcing: A Measurement Based Approach. Eos Trans. AGU, 85(47), Fall Meet. Suppl. 2004, Abstract # A21E-09
Atmospheric aerosol introduces one of the largest uncertainties when quantifying the anthropogenic impact on the Earth-Atmosphere-System. Aerosol (climate) forcing estimates are usually based on simulations with global models. With increasing detail on atmospheric properties (via in-situ samples or remote sensing from ground or space) now, sufficient measurements are available to explore a measurement based approach (when quantifying the aerosol impact on climate). Based on a data synergy of ground statistics (AERONET: aerosol composition) and remote sensing from space (MODIS/MISR: aerosol concentration and distribution, MODIS: solar surface albedo, ISCCP: cloud cover/ vertical distribution), for the year 2000/2001 global monthly simulated fields for clear-sky and all-sky forcing are presented, where clear-sky estimates are compared to CERES data. In addition forcing detail forcing on location (atmosphere versus surface) and anthropogenic contribution (by considering only sub-micron aerosol sizes) is provided.
