Special Issue Information

Dear Colleagues,

Long-term exposure to air pollution not only adversely affects human health but also has serious impacts on the climate and ecosystems. It is important to continuously monitor and predict air quality to assess its impact on human health and the environment. Air quality monitoring is usually conducted through point-based in situ measurements, but the spatial coverage is limited due to the lack of stations covering a large area. Satellite-based aerosol information is widely used as the key parameter to monitor and forecast air quality, not only the local scale but also on the global scale. Many previous studies have adopted various approaches (e.g., data assimilations (DA), artificial intelligence (AI), and a combination of DA and AI) to improve the their model’s performance. The aim of this Special Issue is to explore the latest advancements in satellite remote sensing of atmospheric aerosols for air quality applications. We invite submissions that showcase innovative methodologies, techniques, and applications related to remote sensing analysis in the context of aerosol monitoring. We welcome research articles, reviews, and case studies that address the following topics:

  • Satellite remote sensing data acquisition and preprocessing techniques for aerosol monitoring.
  • Development and validation of algorithms and models for satellite-based retrieval of aerosol properties.
  • Integration of remote sensing data with other sources of information, such as ground-based observations, for comprehensive aerosol assessments.
  • Applications of satellite remote sensing in air quality monitoring, including source attribution and regional-scale variability analysis.
  • Evaluation of the effectiveness of satellite remote sensing in informing regulatory and policy actions to reduce air pollution.

Atmospheric aerosols affect climate change, air quality, and human health. The aerosol optical depth (AOD) is a widely utilized parameter for estimating the concentration of atmospheric aerosols. Consequently, continuous AOD monitoring is crucial for environmental studies. However, a method to continuously monitor the AOD throughout the day or night remains a challenge. This study introduces a method for estimating the All-Day AOD using ground air quality and meteorological data. This method allows for the hourly estimation of the AOD throughout the day in the Beijing–Tianjin–Hebei (BTH) region and addresses the lack of high temporal resolution monitoring of the AOD during the nighttime. The results of the proposed All-Day AOD estimation method were validated against AOD measurements from Advanced Himawari Imager (AHI) and Aerosol Robotic Network (AERONET). The R2 between the estimated AOD and AHI was 0.855, with a root mean square error of 0.134. Two AERONET sites in BTH were selected for analysis. The results indicated that the absolute error between the estimated AOD and AERONET was within acceptable limits. The estimated AOD showed spatial and temporal trends comparable to those of AERONET and AHI. In addition, the hourly mean AOD was analyzed for each city in BTH. The hourly mean AOD in each city exhibits a smooth change at night. In conclusion, the proposed AOD estimation method offers valuable data for investigating the impact of aerosol radiative forcing and assessing its influence on climate change. Full article
