Abstract. Aerosol particle number size distributions and hygroscopic properties were measured at a pasture site in the southwestern Amazon region (Rondonia). The measurements performed 11 September-14 November 2002 as part of LBA-SMOCC (Large scale Biosphere atmosphere experiment Amazonia - SMOke aerosols, Clouds, rainfall Climate), cover later dry season (with heavy biomass burning), transition period, onset wet period. Particle with DMPS (Differential Mobility Sizer, 3-850nm) an APS...

Abstract The Observations and Modeling of the Green Ocean Amazon 2014–2015 (GoAmazon2014/5) experiment took place around urban region Manaus in central Amazonia across 2 years. pollution plume was used to study susceptibility gases, aerosols, clouds, rainfall human activities a tropical environment. Many aspects air quality, weather, terrestrial ecosystems, climate work differently tropics than more thoroughly studied temperate regions Earth. GoAmazon2014/5, cooperative project Brazil,...
Abstract Between 1 September and 4 October 2014, a combined airborne ground-based measurement campaign was conducted to study tropical deep convective clouds over the Brazilian Amazon rain forest. The new German research aircraft, High Altitude Long Range Research Aircraft (HALO), modified Gulfstream G550, extensive instrumentation were deployed in near Manaus (State of Amazonas). part German–Brazilian Aerosol, Cloud, Precipitation, Radiation Interactions Dynamics Convective Cloud...
This paper presents an overview of the results from first major mesoscale atmospheric campaign Large‐Scale Biosphere‐Atmosphere Experiment in Amazonia (LBA) Program. The campaign, collocated with a Tropical Rainfall Measuring Mission (TRMM) satellite validation campaigns, was conducted southwest Rondônia January and February 1999 during wet season. Highlights on interaction between clouds, rain, underlying landscape through biospheric processes are presented discussed.
Abstract Measurements of energy partition for Amazonian forest made with novel eddy correlation equipment are presented eight dry days in September 1983. These interpreted to provide estimates the aerodynamic and surface resistance this vegetation type. Daily total evaporation a transpiring canopy accounts 70% available radiant energy, is two thirds conventional potential evaporation. The results used an initial calibration simple, physically based model daily rain forest.
Este trabalho busca apresentar, de uma maneira compacta, os principais resultados científicos já alcançados pela comunidade brasileira e mundial sobre pesquisas na Amazônia. Aborda-se o paleoclima da região, bem como as características atuais, em termos temperatura do ar distribuição chuvas. São discutidos sistemas atmosféricos atuantes tais linhas instabilidade, brisa fluvial, teleconexões com El-Niño, interação frontais no sul país, friagens, além variabilidade clima nas escalas...
The aerosol characterization experiment performed within the Large‐Scale Biosphere‐Atmosphere Experiment in Amazonia–Smoke, Aerosols, Clouds, Rainfall and Climate (LBA‐SMOCC) field carried out Rondônia, Brazil, period from September to November 2002 provides a unique data set of size‐resolved chemical composition boundary layer over Amazon Basin intense biomass‐burning onset wet season. Three main periods were clearly distinguished on basis PM 10 concentration trend during experiment: (1)...
CHUVA, meaning “rain” in Portuguese, is the acronym for Cloud Processes of Main Precipitation Systems Brazil: A Contribution to Cloud-Resolving Modeling and Global Measurement (GPM). The CHUVA project has conducted five field campaigns; sixth last campaign will be held Manaus 2014. primary scientific objective contribute understanding cloud processes, which represent one least understood components weather climate system. campaigns were designed investigate specific tropical regimes. first...
Long-term measurements of the albedo tropical forest and ranch land have been made at three paired sites in Brazil. The mean albedo, 0.134, is slightly higher than value that has generally used GCM deforestation simulations, while 0.180, lower usually used. monthly means daily all a well-defined seasonal variation not due to effects changing solar elevation angle or variations cloudiness, but correlated with soil moisture. shows some month variation, there no clearly defined trend.
Abstract Measurements from the first comparative study of climate over Amazonian tropical forest and an embedded deforested clearing are presented. Observations comprise a continuous 60‐day run data mid‐October to mid‐December 1990, covering end dry season beginning wet season. Mean hourly observations calculated for whole period; two 10‐day periods, one in at start Much greater variation weather variables was observed compared with forest. While mean values temperature specific humidity...
Abstract We describe the salient features of a field study whose goals are to quantify vertical distribution plant-emitted hydrocarbons and their contribution aerosol cloud condensation nuclei production above central Amazonian rain forest. Using observing systems deployed on 50-m meteorological tower, complemented with tethered balloon deployments, aerosols was determined under different boundary layer thermodynamic states. The forest emits sufficient reactive hydrocarbons, such as isoprene...
The atmospheric boundary layer height (zi) is a key parameter in the vertical transport of mass, energy, moisture, and chemical species between surface free atmosphere. There lack long-term continuous observations zi, however, particularly for remote regions, such as Amazon forest. Reanalysis products, ERA5, can fill this gap by providing temporally spatially resolved information on zi. In work, we evaluate ERA5 estimates zi (zi-ERA5) two locations corrected them means ceilometer,...
Abstract A tethered balloon‐sampling platform was used to study biogenic volatile organic compounds (BVOCs) in the atmospheric boundary layer three distinct moist tropical forest ecoregions, as well an extensive pasture area, Amazonia. Approximately 24–40 soundings, including many four VOC samples collected simultaneously at various altitudes, were made each site. Concentrations mixed increased during morning hours and relatively constant midday through afternoon. Since most important...

High-quality atmospheric CO2 measurements are sparse in Amazonia, but can provide critical insights into the spatial and temporal variability of sources sinks . In this study, we present first 6 years (2014-2019) continuous, high-precision at Amazon Tall Tower Observatory (ATTO, 2.1°S, 58.9°W). After subtracting simulated background concentrations from our observational record, define a regional signal ( ΔCO2obs ) that has marked seasonal cycle with an amplitude about 4 ppm. At both...
