General description
We concentrate on measurement-based assessments
(e.g., from ground-based networks, satellite remote sensing, and intensive
field experiments) of aerosols and their direct radiative effect on solar
radiation, supplemented by a couple of global aerosol model simulations. Model
simulations are also integrated with satellite retrievals to better characterize
global distributions of aerosol optical depth using an optimum interpolation approach.
The assessment is conducted both globally and regionally (over 13 zones with
their divisions shown in a figure below. ).

This image shows The 13 zones used for optimum interpolation of aerosol optical depth. The background depicts the annual
average aerosol optical depth at 550 nm for 2001 derived from MODIS, MISR and
GOCART with a data assimilation approach.

Since its inception in 1993, the AERONET has been collecting a full
set of aerosol properties needed for aerosol radiative effect calculations for both
fine-mode and coarse-mode aerosols over 203 stations around the globe. These valuable
data offer an opportunity of providing the research community with a ground-based
baseline product of aerosol direct radiative effect [Zhou et al., 2005]
for evaluating satellite- and model-based estimate of aerosol direct effect.
It can also serve as an important constraint in formulating a strategy of
deriving aerosol direct effect/forcing from a constellation of multiple
satellites in the near future.
