abstract = {A demonstration study to examine the feasibility
of retrieving dust radiative effects based on combined satellite
data from MODIS (Moderate Resolution Imaging Spectroradiometer),
CERES (Clouds and the Earth’s Radiant Energy
System) and CALIOP (Cloud-Aerosol Lidar with Orthogonal
Polarization) lidar vertical profiles along their orbit
is presented. The GAME (Global Atmospheric Model) radiative
transfer model is used to estimate the shortwave and
longwave dust radiative effects below the CALIPSO (Cloud-
Aerosol Lidar and Infrared Pathfinder Satellite) orbit assuming
an aerosol parameterization based on the CALIOP vertical
distribution at a horizontal resolution of 5 km and additional
AERONET (Aerosol Robotic Network) data. Two
study cases are analyzed: a strong long-range transport mineral
dust event (aerosol optical depth, AOD, of 0.52) that
originated in the Sahara Desert and reached the United Kingdom
and a weaker event (AOD D0.16) that affected eastern
Europe. The radiative fluxes obtained are first validated
in terms of radiative efficiency at a single point with space–
time colocated lidar ground-based measurements from EARLINET
(European Aerosol Research Lidar Network) stations
below the orbit. The methodology is then applied to
the full orbit. The strong dependence of the radiative effects
on the aerosol load (and to a lesser extent on the surface
albedo) highlights the need for accurate AOD measurements
for radiative studies. The calculated dust radiative effects
and heating rates below the orbits are in good agreement
with previous studies of mineral dust, with the radiative efficiency
obtained at the surface ranging between -80:3 and
-63:0Wm-2 for lower dust concentration event and -119:1
and -79:3Wm-2 for the strong event. Thus, results demonstrate
the validity of the method presented here to retrieve
2-D accurate radiative properties with large spatial and temporal
coverage.},
