Systematic Evaluation of Four Satellite AOD Datasets for Estimating PM2.5 Using a Random Forest Approach

Abstract: The latest epidemiological studies have revealed that the adverse health effects of PM2.5 have impacts beyond respiratory and cardio-vascular diseases and also affect the development of the brain and metabolic diseases. The need for accurate and spatio-temporally resolved PM2.5 data has thus been substantiated. While the selective information provided by station measurements is mostly insufficient for area-wide monitoring, satellite data have been increasingly applied to comprehensively monitor PM2.5 distribut… Show more

“…However, such data is not yet available to our knowledge for the entire BW and the time period under investigation. A possible addition to the variables considered could be wind speed, wind direction and boundary layer height since these parameters have shown a large impact on the variability of particulate matter 59 , 60 . Furthermore, boundary layer height and showed the strongest positive correlation among all the analyzed variables in 57 .…”

“…On the other hand, the use of satellite data and atmospheric reanalysis models provides estimates on a global scale and continuous coverage, including remote and poorly monitored areas (Handschuh;Erbertseder;Baier, 2023). In this context, by combining satellite data, in situ measurements and atmospheric models, the Copernicus Atmosphere Monitoring Service (CAMS) plays a crucial role in providing accurate estimates of AOD on a global scale (Garrigues et al, 2022).…”

“…Unlike the works in Refs. 20 to 22 that mostly exploit single-platformed satellite AOD products, a systematic evaluation is performed using RF approach 23 for estimating PM 2.5 using four different satellite AOD datasets. Another deep-learning-based forecasting technique, long short-term memory (LSTM), demonstrated its capability to determine the wind forecasts accurately for predicting solar energy using satellite data.…”
