| Abstract | In Central Brazil every year large areas of forest, cerrado and pasture land are burned emitting primary carbonaceous aerosols into the atmosphere. These interfere with the radiative budget, affecting directly the amount of solar radiation that is reflected and scattered back to space, and partly absorbed by the atmosphere. The long wave terrestrial radiation is also affected. Aerosols also affect cloud microphysics acting as cloud condensation nuclei (CCN), modifying the precipitation pattern and the cloud albedo. During the South American burning season, aersosols have a significant impact on local and regional air quality affecting visibility and human health by particle inhalation causing pulmonary diseases. The recognition of atmospheric aerosols importance led to the necessity of quantifying and optimizing its sources, distributions and sinks in the troposphere to improve simulations with atmospheric chemical models. An improvement of the aerosol representation in such models can be achieved through data assimilation methods including available aerosol observations. In this study an assimilation system was used based on the three dimensional variational data assimilation method (3D-VAR) using the Coupled Chemical-Aerosol-Tracer Transport - Brazilian Regional Modeling System (CCATT-BRAMS). The assimilated observations are mass concentration (MC) of particular matter smaller than 2.5 µm (PM2.5). The observations were collected in October 2007, during the Cloud-Aerosol Interaction Measurements (CLAIM) campaign, which took place in the region of the city Alta Floresta in the state of Mato Grosso, Brazil. The measurements of PM2.5 were collected by a DATARAM instrument aboard the aircraft that collected information with 10s or 30s frequency. During the campaign 17 flights were carried out, 13 of which could be used in this study. In this paper we present the data and its assimilation results, evaluate its improvement of the model simulation and discuss its general impact on the chemical state of atmosphere. |
