| Resumo | The Amazon is one of the most important tropical forests in the world because it is a key in the regulation of the global climate. It is the world's largest rainforest, where interactions between the forest and the atmosphere are fundamental to rainfall throughout South America and have an indirect effect on all the regions around the world. Furthermore, the Amazon region may be a source of aerosol that will act as cloud condensation nuclei (CCN). During the rainy season over the Amazon region, in which intense convective activity associated with the South America Monsoon System (SAMS) prevents fires, the primary sources of aerosols include biogenic emissions, dust from the Sahara Desert, and emissions from burning biomass transported from Africa. Besides that, the downward transport of aerosols from the upper troposphere (UT) has been considered a source of particles to the lower troposphere. The particles in the UT over the tropics region have been one of the largest aerosol reservoirs in the atmosphere, which could be from primary aerosols, such as dust, organic carbon and black carbon or secondary aerosol formed by trace gases in the free troposphere. The existence of an aerosol layer at the tropopause level has been observed during June, July, and August in Asia and North America (Asian Tropopause Aerosol Layer - ATAL and North American Tropopause Aerosol Layer - NATAL, respectively) associated with the deep convection of the Monsoons System. Therefore, the aerosol enhancement in the UT and lower stratosphere (LS) and the formation of an aerosol layer over the Amazon region associated with the deep convection of the SAMS during the austral summer are investigated. In the past, field campaigns over South America (SA) (GoAmazon2014/5 experiment) showed aerosol enhancement in the UT. They suggested that new aerosol particles are formed in the UT from biogenic volatile organic material that goes up by upward transport associated with the deep convection. The enhancement of aerosol backscatter values over SA is observed from October to January; it gradually decreases during the following months. The aerosol backscatter inferred from MERRA-2 Reanalysis showed a maximum value of the 2.24x10-5 km-2sr-1 over the Amazon during November and December. The results showed the first evidence of the existence of the South American Tropopause Aerosol Layer (SATAL) that covers the tropical SA and vertically extends up to 80hPa (approximately 18 km), similar to ATAL, and NATAL. The aerosol backscatter inferred from MERRA-2 reanalysis was validated using the attenuated backscatter by CALIOP from CALIPSO satellite. However, field campaigns such as the CAFE-BRAZIL campaign (Chemistry of the Atmosphere: Field Experiment in Brazil), which will be during December/2022 and January/2023 using the HALO (High Altitude Long Range Aircraft) aircraft, are necessary to study the formation of SATAL. | |||
