Abstract Air pollution from road transport-related tailpipe emissions is a well-documented risk to human health. This study assesses the health impacts of these under business-as-usual and various policy scenarios across 186 countries territories, including 13,135 urban areas, until 2040, at 1km resolution. We evaluate for 15 based on different combinations key emission control measures. use GEOS-Chem Adjoint v35n pollutant concentration modeling. estimate PM 2.5 ozone-attributable premature...
The Latin American Lidar Network (LALINET) is the aerosol lidar network operating over South America. LALINET now an operative performing a schedule of routine measurements and, currently, composed by 9 stations distributed main objective to generate consistent and statistically relevant database enhance understanding particle distribution continent its direct indirect influence on climate. creation un-biased spatiotemporal requires throughout review two pillars: instrumentation data...
The so-called Metropolitan Area of São Paulo, one the largest megacities in world, faces several problems related to air quality due high concentrations aerosols produced either by local sources or long-range transporting. Concerned with elevated aerosol and their impact climate changes inside MASP, a measurement campaign were conducted during South hemisphere winter 2012, when low temperatures level precipitation contribute poor dispersion aerosols. A Raman Lidar system monitoring stations...
Moodle is a well-known open source system to support teaching and learning through the web. It provides Quiz, tool for assessment, which also adopted by large community along world. Another that allows automatic assessment within iAssign package. means integrating interactive Learning Modules (iLM) Moodle, empowering it with intense activities concerning specific issues implemented in iLM. However, such tools present some limitations prevent their users take more benefit of question types...
Abstract Due to the COVID‐19 pandemic, governments imposed several mobility restrictions which can be used evaluate their impact on air quality and generate better‐targeted policies improve it. Therefore, this study aimed define sustainable mitigation measures reduce pollution based quantifying impacts of during pandemic in Portugal. Thus, hourly concentrations PM 10 , 2.5 NO 2 O 3 CO SO were obtained from Portuguese Air Quality Monitoring Network. Data was then divided into six periods...
Brazil has an important role in the biomass burning, with detection of approximately 100,000 burning spots a single year (2007). Most these occur southern part Amazon basin during dry season (from August to november) and emissions reach southeast country, highly populated region serious urban air pollution problems. With growing demand on biofuels, sugarcane is considerably expanding state Sao Paulo, being strong contributor bad quality this region. In main land use are pasture crop, that...
Characterization of atmospheric emissions from industrial flare stacks represents a challenge in measurement techniques because it is extremely difficult to determine the real-time concentrations combustion products by situ sampling, due stack height, sensor calibration difficulties, and dynamics oscillations emission patterns. A ground based laser remote sensing (LIDAR) system has been developed for continuous monitoring an oil refinery located approximately 400 m instrument. The able...

Atmospheric aerosol particles have received much attention in recent years due to their importance climate change. The influence of these on Earth's radiative budget depends a number factors, including size distribution and chemical composition. This work addresses particular property aerosols, namely, the extent which they affinity for water vapor. increase resulting from vapor uptake has important implications direct scattering radiation cloud droplets formation. We used single-wavelength...
The central and western portion of the Sao Paulo State has large areas sugar cane plantations, due to growing demand for biofuels, production is increasing every year. During harvest period some plantation are burnt a few hours before manual cutting, causing significant quantities biomass burning aerosol be injected into atmosphere. August 2010, field campaign been carried out in Ourinhos, situated south-western region State. A 2-channel Raman Lidar system two meteorological S-Band Doppler...
The determination of the amount water vapor in atmosphere using lidar is a calibration dependent technique. Different collocated instruments are used for this purpose, like radiossoundings and microwave radiometers. When there no available, an independente lamp mapping technique can be used. Aiming to stabilish independ six channels Nd-YAG Raman system located at Center Lasers Applications (CLA), S˜ao Paulo, Brazil, optical characterization was first performed reference tungsten lamp. This...
Aerosol hygroscopicity is a property that reveals the ability of an aerosol particle to grow under increasing values relative humidity. The hygroscopic behavior has significant effect on radiative properties aerosols, and therefore cloud formation, aerosol-cloud interaction and, consequently, Earth's climate. In this work, Raman LIDAR used determine growth factor f<sub>β</sub> (RH) unperturbed, ambient atmospheric conditions in well-mixed boundary layer São Paulo metropolitan city. To aim,...
Aerosol Higroscopicity addresses a particular aspect of aerosol, namely, the extent to which they have an affinity for water vapor. The size increase aerosol particles resulting from uptake vapor has important implications direct scattering radiation and, under right circumstances, form cloud droplets. Ultimately this effect should on Earth's radiative budget and belongs category well known as indirect effect. For purposed we used single-wavelength backscatter LIDAR (532 nm), combined with...

We compare the performance of some available atmospheric models for atmosphere Sao Paulo (Brazil) to be used in case absence radio-sounding data given day.We developed our own model (SPm) from historic order create a local model.By performing inversions lidar signals (distributed over year), we could benchmark against data.SPm and ISA-15N show smallest deviation represent, therefore, best fallback this southern latitude.
Elastic backscatter LIDAR systems have been used to determine aerosol profile concentration in several areas such as weather, pollution and air quality monitoring. In order the extinction backscattering profiles, Klett inversion method is largely used, but this suffers from lack of information since there are two unknown variables be determined using only one measured signal, assumption ratio (the relation between coefficients) needed. When a Raman system inelastic signal affected by not...
The air quality in the state of Sao Paulo was evaluated during first general State plan mobility restrictions due to COVID-19 pandemics (24th March 31st May 2020). Nitrogen dioxide (NO2), ozone (O3), particulate matter with a diameter less than 10 μm (PM10) and 2.5 (PM2.5) sulphur (SO2) concentrations were assessed all cities monitoring station compared historical data. Linear regression models built quantify linear relation between isolation index concentration each pollutant studied...
