Absorbing aerosols monitoring over remote regions
Although the Earth???s atmosphere consists primarily of gases, aerosols and clouds play important roles in the Earth???s energy balance and climate. Aerosols alter the Earth???s energy budget directly by scattering and absorbing radiation and indirectly by modifying cloud microphysical and radiative...

Although the Earth???s atmosphere consists primarily of gases, aerosols and clouds play important roles in the Earth???s energy balance and climate. Aerosols alter the Earth???s energy budget directly by scattering and absorbing radiation and indirectly by modifying cloud microphysical and radiative properties. Evaluation of aerosol effects on climate must take into account high spatial and temporal variation of aerosol amounts and properties as well as the aerosol interactions with clouds and precipitation. Combustion of carbonaceous fuels for the production of energy inevitably results in the emission of gas and particulate air pollutants. A large fraction of the emitted particles are light absorbing carbonaceous aerosols that exhibit very large optical absorption across the spectrum. The most measured light absorbing carbonaceous aerosol is black carbon (BC), a unique primary tracer for combustion emissions as it is not emitted by any other sources. In the project ???Absorbing aerosols monitoring over remote regions???, we have used a lightweight aircraft to obtain information on the BC and other light absorbing carbonaceous aerosols concentrations.
