Resumo
Definiu-se como abordagem principal, estimar a variabilidade de determinados poluentes diária e semanalmente (principalmente MP10 e NO2, porém há ainda o estudo de NO e O3) e também as condições meteorológicas (velocidade dos ventos e radiação global) preponderantes no extremo oeste paulista, principalmente no município de Presidente Prudente, SP. A partir disso, decidiu-se utilizar as médias horárias por estação, para que fosse viável observar a curva horária de cada poluente e aspecto meteorológico estudado. Instituiu-se uma determinada metodologia que permitisse a análise desses parâmetros em uma quantidade estipulada de meses, foi exequível o engendramento de: gráficos, quadros, painéis e diversas figuras, que possibilitasse uma melhor análise e estimativa da temática, tendo ainda, produtos gerados de fácil cognição, isto é, após a elaboração do estudo mirando nas variáveis horárias, tornou-se possível a geração de produtos com a escala semanal que proporcionam uma análise mais ampla sobre os poluentes no local de estudo. Através dos painéis gerados, tem-se todas as perspectivas semanais e mensais relacionadas a diversos parâmetros meteorológicos e de poluentes atmosféricos, a partir disso é possível obter uma análise que englobe todos os fatores relevantes a fim de observar a influência entre esses dois tipos de parâmetros. Fez-se factível o entendimento de situações em que há precipitações na localidade de estudo, aplicando uma escala temporal e física, observa-se a remoção de poluentes atmosféricos após realizar comparações e executar o estabelecimento de determinado referencial diário. Alicerçado nisso, compreende-se as possíveis relações e desdobramentos entre a poluição do ar e índices meteorológicos.
It was defined as the main approach, to estimate the variability of certain pollutants on a daily and weekly basis (mainly MP10 and NO2, but there is still the study of NO and O3) and also the meteorological conditions (wind speed and global radiation) prevailing in the extreme west of São Paulo, mainly in the city of Presidente Prudente, SP. From this, it was decided to use hourly averages per station, so that it would be feasible to observe the hourly curve of each pollutant and meteorological aspect studied. A certain methodology was instituted to allow the analysis of these parameters in a stipulated number of months, it was feasible to engineer graphs, charts, panels and several figures, which would allow a better analysis and estimation of the theme, having also generated products of easy cognition, i.e., after the elaboration of the study looking at the hourly variables, it became possible to generate products with a weekly scale that provide a broader analysis of the pollutants in the place of study. Through the generated panels, one has all the weekly and monthly perspectives related to various meteorological parameters and air pollutants, from this it is possible to obtain an analysis that encompasses all relevant factors in order to observe the influence between these two types of parameters. It was made feasible to understand situations in which there is precipitation in the place of study, applying a temporal and physical scale, to observe the removal of atmospheric pollutants after making comparisons and performing the establishment of a certain daily benchmark. Based on this, the possible relationships and developments between air pollution and meteorological indices are understood.
