Smoke, Clouds, and Radiation - Brazil

Project Description
The Smoke, Clouds, and Radiation - Brazil was one of several planned
SCAR experiments conducted on August 13 - September 11, 1995 in
Central Brazil. The objective of the SCAR-B project was to study the
radiative effects of burning biomass smoke and aerosols on clouds and
the climate.
The Smoke/Sulphate Clouds And Radiation (SCAR) experiments are a
series of field experiments whose main goal is to better understand
the impact of biomass burning and urban/industrial aerosol on the
atmosphere and therefore climate. During each SCAR experiment in situ
and remotely sensed data are measured simultaneously with the
objective to characterize most of the physical and chemical components
of the atmospheric aerosol, trace gases and clouds, the Earth's
surface, the radiation field and the properties of fires. The SCAR
series of experiments is designed to try to narrow some of the
uncertainties associated with the affect atmospheric aerosols have on
climate, either directly or indirectly, as well as to generate
information and prepare data for the evaluation of algorithms for
remote sensing from the Moderate Resolution Imaging Spectroradiometer
(MODIS) sensor on the Earth Observing System (EOS), planned for launch
in 1998. There are three planned SCAR experiments with the main
experiment to focus on the tropical biomass burning environment which
took place in Brazil during August/September 1995. The first two SCAR
experiments were conducted in the Eastern United States Atlantic
region (SCAR-A) in 1993 and in California and the Pacific Northwest
(SCAR-C) in 1994. SCAR-A was designed to measure the properties of
urban and industrial pollution dominated by sulfate particles. SCAR-C
measured the properties and radiative effects of smoke aerosol and
trace gases emitted from wild and prescribed fires in the Pacific
Northwest of the US. The SCAR series of experiments have been a
collaborative effort between United States and Brazilian scientists
and future collaborations between the two countries is expected to
continue for the long-term monitoring of trace gas and particle
emissions and their impact on the Earth's atmosphere and climate.
