Clear-SKY-Saeulenexperiment (ACE-2)

Description: Das Projekt "Clear-SKY-Saeulenexperiment (ACE-2)" wird vom Umweltbundesamt gefördert und von Leibniz-Institut für Troposphärenforschung e.V. durchgeführt. Physical and chemical properties of the aerosol will be measured in the vertical column to be used to accurately predict the integrated direct effect of aerosols on radiative transfer. In that column, the experiment will derive the aerosol parameters which are necessary to quantify the direct radiative forcing of the tropospheric aerosol. These data will provide the radiative reference point for all air-borne radiative measurements within ACE-2. The satellites involved in this study will then be used to relate the direct radiative forcing derived in CLEARCOLUMN and in other columnar experiments to the larger North Atlantic region. The ground-based columnar extinction- and scattering measurements are carried out at three elevations, on three airborne platforms in the vicinity of a LIDAR beam. Unidisciplinary and multidisciplinary local closure will be derived at different altitudes in the boundary layer and free troposphere from radiative and physico-chemical aerosol information. The vertically integrated LIDAR information will be compared to columnar extinction data derived from ground-based and air- and space-borne radiometers (supported by data on water-leaving radiances from ship and airborne platforms) in order to derive column closure of aerosol optical properties. The radiative flux divergences from airborne measurements at different altitudes will be compared to corresponding results derived by means of radiative transfer modelling from LIDAR-profiles and airborne measurements within the aerosol layer in order to quantify the direct radiative forcing of the aerosol layer.
