ResumoThe nucleation of atmospheric vapours is an important source of new aerosol particles that can subsequently grow to form cloud condensation nuclei in the atmosphere1 . Most field studies of atmospheric aerosols over continents are influenced by atmospheric vapours of anthropogenic origin (for example, ref. 2) and, in consequence, aerosol processes in pristine, terrestrial environments remain poorly understood. The Amazon rainforest is one of the few continental regions where aerosol particles and their precursors can be studied under near-natural conditions35, but the origin of small aerosol particles that grow into cloud condensation nuclei in the Amazon boundary layer remains unclear68. Here we present aircraft- and ground-based measurements under clean conditions during the wet season in the central Amazon basin. We find that high concentrations of small aerosol particles (with diameters of less than 50 nanometres) in the lower free troposphere are transported from the free troposphere into the boundary layer during precipitation events by strong convective downdrafts and weaker downward motions in the trailing stratiform region. This rapid vertical transport can help to maintain the population of particles in the pristine Amazon boundary layer, and may therefore influence cloud properties and climate under natural conditions.

ResumoThe 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.

ResumoAtmospheric aerosol refers to a group of solid or liquid particles suspended in the atmosphere that has an impact on the planet's climate by altering the radiative balance. Its effects can be direct or indirect. Aerosols serve as the starting point for condensation and the development of droplets known as Cloud Condensation Nuclei (CCN). In addition to interacting with radiation and affecting the optical characteristics of clouds, CCNs can alter the formation of droplets and ice crystals, cloud cover, and precipitation. Aerosols in the lower troposphere either move up to the upper troposphere/lower stratosphere (UT/LS) or, in a process known as new particle creation, trace gases move up to the UT and create new particles by condensing gases in the free atmosphere. Thus, in this study we analyzed the presence South American Tropopause Aerosol Layer (SATAL), an aerosol layer in the upper troposphere/lower stratosphere (UT/LS) in South America, over the Amazon region to characterize this layer. For that, it was used Aerosol Extinction 532 nm (AE532) from MERRA-2, for the period January/2002 to December/2021 and aerosol measurements in the upper troposphere from High Altitude Long Range Aircraft (HALO) airplane. The HALO measurements were made during the GermanBrazilian campaign Chemistry of the Atmosphere: Field Experiment in Brazil (CAFE-Brazil) that took place over the Amazon region during December/2022 and January/2023. Our results from MERRA-2 clearly show the presence of the SATAL over South America, specifically over the Amazon Basin at around 11-14 km height, with seasonal behavior like the ATAL and NATAL (over Asia region and North America, respectively). The maximum AE532 values occurred between October and November, coincident with the starts of the wet season period over South America. SATAL is formed first in the eastern Amazon eastern Amazon Basin, then moves to the Southern Amazon, where it weakens in December-January and finally dissipates in February-March. Because SATAL's biggest peak occurs between October and November, our preliminary findings imply that SATAL is generated by organic aerosols, most likely associated with the dry season. Once, the source of aerosols probably is in the lower troposphere, the updraft mass flux from the convective activity during the active phase of the South American Monsoon System (SAMS) make them go up. Particles in the UT/LS have been one of the largest aerosol reservoirs in the atmosphere, and they can act as CCN in remote regions.

ResumoBlack carbon (BC) aerosols influence the Earth's atmosphere and climate, but their microphysical properties, spatiotemporal distribution, and long-range transport are not well constrained. This study presents airborne observations of the transatlantic transport of BC-rich African biomass burning (BB) smoke into the Amazon Basin using a Single Particle Soot Photometer (SP2) as well as several complementary techniques. We base our results on observations of aerosols and trace gases off the Brazilian coast onboard the HALO (High Altitude and LOng range) research aircraft during the ACRIDICON-CHUVA campaign in September 2014. During flight AC19 over land and ocean at the northeastern coastline of the Amazon Basin, we observed a BCrich layer at similar to 3.5 km altitude with a vertical extension of similar to 0.3 km. Backward trajectories suggest that fires in African grasslands, savannas, and shrublands were the main source of this pollution layer and that the observed BB smoke had undergone more than 10 d of atmospheric transport and aging over the South Atlantic before reaching the Amazon Basin. The aged smoke is characterized by a dominant accumulation mode, centered at about 130 nm, with a particle concentration of N-acc = 850 +/- 330 cm(-3). The rBC particles account for similar to 15% of the submicrometer aerosol mass and similar to 40% of the total aerosol number concentration. This corresponds to a mass concentration range from 0.5 to 2 mu gm(-3) (1st to 99th percentiles) and a number concentration range from 90 to 530 cm(-3). Along with rBC, high cCO (150 +/- 30 ppb) and cO3 (56 +/- 9 ppb) mixing ratios support the biomass burning origin and pronounced photochemical aging of this layer. Upon reaching the Amazon Basin, it started to broaden and to subside, due to convective mixing and entrainment of the BB aerosol into the boundary layer. Satellite observations show that the transatlantic transport of pollution layers is a frequently occurring process, seasonally peaking in August/September. By analyzing the aircraft observations together with the long-term data from the Amazon Tall Tower Observatory (ATTO), we found that the transatlantic transport of African BB smoke layers has a strong impact on the northern and central Amazonian aerosol population during the BB-influenced season (July to December). In fact, the early BB season (July to September) in this part of the Amazon appears to be dominated by African smoke, whereas the later BB season (October to December) appears to be dominated by South American fires. This dichotomy is reflected in pronounced changes in aerosol optical properties such as the single scattering albedo (increasing from 0.85 in August to 0.90 in November) and the BC-to-CO enhancement ratio (decreasing from 11 to 6 ngm 3 ppb 1). Our results suggest that, despite the high fraction of BC particles, the African BB aerosol acts as efficient cloud condensation nuclei (CCN), with potentially important implications for aerosol-cloud interactions and the hydrological cycle in the Amazon.
