“…For the same study area and data set , this correlation could significantly change throughout the year due to the variable source and meteorological changes. Empirical studies of the relationship between PM 2.5 and AOD have been reported in various regions of the world (Gupta et al, 2006;Ho and Christopher, 2009;Kusmierczyk-Michulec, 2011), such as the US (Wang and Christopher, 2003;Zhang et al, 2009), the densely populated and industrially developed areas of Asia (Kumar et al, 2007;Mukai et al, 2007), and Europe (Kacenelenbogen et al, 2006;Schaap et al, 2009;Pelletier et al, 2007;Dinoi et al, 2010). Nevertheless, as noted in the work of Schaap et al (2009), locally obtained relationships between AOD and particle matter (PM) cannot be easily extrapolated to other areas owing to variations in different source types, PM composition, and meteorology.…”

En este estudio se evalúa la influencia de partículas PM 10 en el espesor óptico de aerosoles en los Andes centrales del Perú, además de analizar y establecer los patrones de circulación en la región desde julio hasta octubre de 2017. Se considera este periodo en particular porque los mayores eventos de quema de biomasa se registran generalmente durante esos meses. Se utilizó el modelo regional de transporte meteorológico-químico WRF-Chem (versión 3.7) con el Inventario de Incendios del NCAR (FINN) y los datos de espesor óptico de aerosoles (EOA) de la Red de Monitoreo de Redes Robóticas de Aerosoles (AERONET), que cuenta con un fotómetro solar CIMEL ubicado en el observatorio de Huancayo, la ciudad más importante del altiplano central del Perú. La simulación empleó un único dominio con un tamaño de cuadrícula de 18 km y 32 niveles verticales. Los resultados mostraron un incremento en las concentraciones de PM 10 con un aumento en el número de brotes de incendio y en el EOA durante julio, agosto y septiembre. Por el contrario, en octubre se registró una ligera disminución de las concentraciones de PM 10. Además, las condiciones meteorológicas no favorecieron la ocurrencia de brotes de incendios en el valle del Mantaro durante todo el período de estudio; sin embargo, un aumento en las precipitaciones redujo las concentraciones de aerosoles en octubre. Además, aunque los movimientos verticales que prevalecían sobre los Andes centrales eran ascendentes, descendían a lo largo de la costa peruana, favoreciendo y dificultando la dispersión de los aerosoles en el primer y segundo caso, respectivamente. Finalmente, los autores evaluaron, analizaron y confirmaron la influencia de la quema de biomasa sobre el EOA en la región estudiada.

“…12 The disadvantage is the potential for censured data because of cloud cover, other atmospheric conditions, or technical issues that limit satellite measurements. 13 The current study is focused on Athens, Greece during the year of 2004 with the overall goal to (1) demonstrate a systemized process for aligning satellite AOD data by geographic location and time, (2) evaluate the ability to apply imputation methods to AOD censored data, and 3) confirm that AOD data can be used satisfactorily to investigate the association between AOD and health impacts using an example of hospital admissions for childhood asthma.…”

An understanding of human health implications from atmosphere exposure is a priority in both the geographic and the public health domains. The unique properties of geographic tools for remote sensing of the atmosphere offer a distinct ability to characterize and model aerosols in the urban atmosphere for evaluation of impacts on health. Asthma, as a manifestation of upper respiratory disease prevalence, is a good example of the potential interface of geographic and public health interests. The current study focused on Athens, Greece during the year of 2004 and (1) demonstrates a systemized process for aligning data obtained from satellite aerosol optical depth (AOD) with geographic location and time, (2) evaluates the ability to apply imputation methods to censored data, and (3) explores whether AOD data can be used satisfactorily to investigate the association between AOD and health impacts using an example of hospital admission for childhood asthma. This work demonstrates the ability to apply remote sensing data in the evaluation of health outcomes, that the alignment process for remote sensing data is readily feasible, and that missing data can be imputed with a sufficient degree of reliability to develop complete datasets. Individual variables demonstrated small but significant effect levels on hospital admission of children for AOD, nitrogen oxides (NOx), relative humidity (rH), temperature, smoke, and inversely for ozone. However, when applying a multivari-able model, an association with asthma hospital admissions and air quality could not be demonstrated. This work is promising and will be expanded to include additional years.
