Long-term three-dimensional distribution and transport of Saharan dust: Observation from CALIPSO, MODIS, and reanalysis data
Abstract Desert dust and sand storms from the Sahara can sometimes be transported thousands of kilometers, causing social and economic damages throughout their path, deteriorating the air quality, and affecting human health. The seasonal climatology and transport pathways of dust aerosols are, therefore, essential to a deeper understanding of the impact of dust on the affected […]
Assessing household fine particulate matter (PM2.5) through measurement and modeling in the Bangladesh cook stove pregnancy cohort study (CSPCS)
Abstract Biomass fuel burning is a significant contributor of household fine particulate matter (PM2.5) in the low to middle income countries (LMIC) and assessing PM2.5 levels is essential to investigate exposure-related health effects such as pregnancy outcomes and acute lower respiratory infection in infants. However, measuring household PM2.5 requires significant investments of labor, resources, and time, which limits the ability […]
Long-term PM2.5 pollution over China: Identification of PM2.5 pollution hotspots and source contributions
Abstract Fine particulate matter, with an aerodynamic diameter ≤ 2.5 μm (PM2.5), is a severe problem in China. The lack of ground-based measurements and its sparse distribution obstruct long-term air pollution impact studies over China. Therefore, the present study used newly updated Global Estimates (V5. GL.02) of monthly PM2.5 data from 2001 to 2020 based on Geographically Weighted Regression (GWR) by […]
Trace gases over land and ocean surfaces of China: hotspots, trends, and source contributions
Abstract Trace gases in the atmosphere (NO2: nitrogen dioxide; SO2: sulfur dioxide) have a major impact on both local and global air quality, human health, climate and ecological conditions. Therefore, the present study investigated 16 years (2005– 2020) of Ozone Monitoring Instrument (OMI) based NO2 and SO2 in Dobson unit (DU) spatiotemporal distributions and variability, SO2/NO2 […]
