Drought Variabilities in Saudi Arabia: Unveiling Spatiotemporal Trends through Observations and Projections
Abstract In the Kingdom of Saudi Arabia (KSA), meteorological drought leads to significant water scarcity and triggers profound social, economic, and environmental challenges. The main aim of this paper is to quantify spatiotemporal variability in drought using precipitation data from 28 meteorological stations (1985–2023) and produce future projections. Drought is expressed in terms of the […]
Sand and Dust Storms Impact on Photovoltaic Panels in Saudi Arabia
Abstract This research aims to assess the spatial potential of solar energy in Saudi Arabia by estimating the total sum and analyzing the spatial variability of solar radiation to determine the best sites for solar energy generation that are least affected by sandstorms in the country. It also explores the effects of sandstorms on solar […]
Community-Level Practice Checklists for Health Protection During Cold Spells in China
Abstract Communities play a crucial role in protecting the health of vulnerable populations such as the elderly, low-income groups, and high-risk individuals during cold spells. However, current strategies for responding to cold spells primarily consist of programmatic policies that lack practicality, specificity, and detailed implementation guidelines for community workers. Therefore, this study aims to identify […]
Assessing the role of socio-economic factors in shaping the temperature-mortality exposure-response relationship in China
Abstract Non-optimal temperatures significantly influence public health. However, the role of socio-economic factors in modulating health risks associated with non-optimal temperatures varies geographically and among different populations. Thus, the meteorological, air quality, health data, and socio-economic indicators were obtained from 23 districts in North and 48 districts in East China, respectively. Employing a two-stage meta-analysis, […]
Investigating Two-dimensional Horizontal Mesh Grid Effects on the Eulerian Atmospheric Transport Model Using Artificial Neural Network
Abstract The complexity of monitoring is compounded by the environmental and health impacts linked to air pollution. The elevated expenses and intricate execution involved in measurements prompt the integration of modeling as a complementary approach alongside monitoring and surveillance efforts. Transport chemistry models like CHIMERE operate deterministically, utilizing meteorological factors, emissions data, boundary conditions, and […]
Unravelling the impacts of stratospheric intrusions on near-surface ozone during the springtime ozone pollution episodes in Lhasa, China
Abstract While air pollution due to fine particulate matter (PM2.5) has been effectively controlled in China; the photochemical pollution characterized by elevated ozone (O3) has emerged as a major concern for air quality improvement. Except for ozone, Lhasa is one of the cleanest cities in China with the lowest annual PM2.5 concentration in 2017. The […]
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 […]
