Abstract. Inventories for global aerosol and precursor emissions have been collected (based on published inventories simulations), assessed prepared the year 2000 (present-day conditions) 1750 (pre-industrial conditions). These datasets establish a comprehensive source emission input to modeling, when simulating impact climate with state-of-the-art component modules. As these modules stratify into dust, sea-salt, sulfate, organic matter soot, all types fields strength recommendations...
In many regions of the world, fires are an important and highly variable source air pollutant emissions, they thus constitute a significant if not dominant factor controlling interannual variability atmospheric composition. This paper describes 41‐year inventory vegetation fire emissions constructed for Reanalysis Tropospheric chemical composition over past 40 years project (RETRO), global modeling study to investigate trends tropospheric ozone other pollutants decades. It is first attempt...
The new Global Wildland Fire Emission Model (GWEM) has been developed on the basis of data from European Space Agency's monthly Burnt Scar satellite product (GLOBSCAR) and results Lund‐Potsdam‐Jena Dynamic Vegetation (LPJ‐DGVM). GWEM computes emissions more than 40 chemical compounds aerosols forest savanna fires. This study focuses an evaluation GLOBSCAR set. version presented here makes use Moderate‐Resolution Imaging Spectroradiometer (MODIS) land cover map. totals for year 2000 are 1741...
Quantifying the contribution of biomass burning to global distribution emissions carbon into atmosphere requires knowledge area burnt. The GLOBSCAR project was initiated in 2001 as part European Space Agency (ESA) Data User Programme, with objective producing incremental monthly maps burnt areas, using daytime data from year 2000 Along Track Scanning Radiometer (ATSR‐2) instrument onboard ESA ERS‐2 satellite. processing system combines use two algorithms representing different approaches...
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that particularly impact Hemisphere. In this article, we present a broad overview of many challenges for understanding chemistry Hemisphere, before focusing on most significant factors differentiate it Northern We sections importance biogenic emissions and fires showing these often dominate over...
Abstract An intercomparison of four regional air quality models is performed in the tropical megacity São Paulo with perspective developing a forecasting system based on model ensemble. Modeled concentrations main regulated pollutants are compared combined observations center, after analyzing spatial scale representativeness monitoring stations. During three contrasting periods characterized by different types pollution events, hourly carbon monoxide (CO), nitrogen oxides (NOx), sulfur...
Abstract. Inventories for global aerosol and precursor emissions, auxiliary information, have been collected, assessed prepared the year 2000 (present-day conditions) 1750 (pre-industrial conditions). These datasets establish a reference input in modeling, when simulating impact on climate with state-of-the-art component modules. modules stratify by type, distinguishing among dust, seasalt, sulfate, organic matter soot. The are also intented to serve as systematic constraints sensitivity...
This paper presents an analysis of ground‐based Aerosol Optical Depth (AOD) observations by the Robotic Network (AERONET) in South America from 2001 to 2007 comparison with satellite AOD product Moderate Resolution Imaging Spectroradiometer (MODIS), aboard TERRA and AQUA satellites. Data 12 observation sites were used primary interest AERONET located or downwind areas high biomass burning activity measurements available for full time range. Fires cause predominant carbonaceous aerosol...
The present study is the first assessment of occupational risk associated with artisanal cashew nut roasting using exposure and effect biomarkers, as well a characterization dispersion analysis released particulate matter (PM). A real-time particle monitor was used to quantify PM1.0, PM2.5 PM10. Furthermore, PM sampled Handi-vol sampler, physicochemical characteristics were determined by SEM-EDS analysis. Trajectories, deposition emitted material calculated NOAA-HYSPLIT model. Urinary...
A 12-year analysis, from 2005 to 2016, of atmospheric aerosol optical properties focusing for the first time on Northeast Brazil (NEB) was performed based four different remote sensing datasets: Moderate Resolution Imaging Spectroradiometer (MODIS), Aerosol Robotic Network (AERONET), Cloud-Aerosol LIDAR with Orthogonal Polarization (CALIOP) and a ground-based Lidar Natal. We evaluated identified distinct types, considering Optical Depth (AOD) Angström Exponent (AE). All analyses show that...
Forecasting urban air quality is important for protecting public health, but current model forecasts are often limited by an inaccurate prescription of pollutant emissions from human activities. We developed a new approach that improves adjusting emission based on observed concentrations in agglomerations key pollutants such as nitrogen oxides, sulfur dioxide, carbon monoxide, particulate matter, and volatile organic compounds. Applying this to the São Paulo metropolitan area, Brazil, we...
South America has experienced severe compound drought-heatwaves (CDHW), exacerbating fires. Recently, the unprecedented Pantanal 2020 fire season (P20F), burning a third of biome, resulted in well-reported local impacts on ecosystem, economy, and health. Nevertheless, long-range ripple effects this event remain unknown. We investigated P20F-related cascading hazards, integrating models, observational satellite-based data. smoke elevated PM2.5 levels SA's most populated area, exceeding WHO...

This is calibrated with half-wave plate using the Δ90° methodology. data from correlated AERONET sunphotometer data, and, when available, CALIPSO satellite data. addition trajectory model (HYSPLIT) used to calculate backward trajectories assess origin dust polluted air parcels. objective create...
Este trabalho apresenta a primeira avaliação das taxas de emissões CO2 oriundas do uso e mudança no da terra na Caatinga, único bioma exclusivamente brasileiro que compreende 844,453 km2 área está localizado Nordeste Brasil. Uma abordagem foi realizada para toda vegetação caatinga presente Estado Rio Grande Norte, uma aproximadamente 52.810km2. Para estimativa CO2, adaptado o modelo INPE - Emission Model (INPE-EM).
