Combining the Emission Preprocessor HERMES with the Chemical Transport Model TM5-MP Atmosphere (IF 2.9) Pub Date : 2024-04-10 Sarah-Lena Seemann, Nikos Daskalakis, Kun Qu, Mihalis Vrekoussis
Emission inventories (EIs) are vital for air quality modeling. Specific research goals often require modifying EIs from diverse data sources, demanding significant code development. In this study, we utilized and further developed the High Elective Resolution Modeling Emission System version three for Global and Regional domains (HERMESv3_gr). This user-friendly processing system was adapted for generating

A Statistical Forecasting Model for Extremes of the Fire Behaviour Index in Australia Atmosphere (IF 2.9) Pub Date : 2024-04-10 Rachel Taylor, Andrew G. Marshall, Steven Crimp, Geoffrey J. Cary, Sarah Harris
The increasing frequency and duration of severe fire events in Australia further necessitate accurate and timely forecasting to mitigate their consequences. This study evaluated the performance of two distinct approaches to forecasting extreme fire danger at two- to three-week lead times for the period 2003 to 2017: the official Australian climate simulation dynamical model and a statistical model

Comparative Experimental Assessment of Pollutant Emission Behavior in Combustion of Untreated and Thermally Treated Solid Biofuels from Spruce Chips and Rapeseed Straw Atmosphere (IF 2.9) Pub Date : 2024-04-05 Jan Malaťák, Jan Velebil, Jiří Bradna, Marián Kučera, Arkadiusz Gendek, Monika Aniszewska, Tatiana Alexiou Ivanova
Biomass energy for heating is going to be part of the spectrum of renewable energy sources. However, biomass combustion produces emissions of various pollutants with negative effects at both local and global scales. To reduce some of the locally important pollutant load, thermally treated biomass fuels may offer a partial solution. In this study, two biomass feedstocks, i.e., spruce chips and rapeseed

Extremely Low Frequency (ELF) Electromagnetic Signals as a Possible Precursory Warning of Incoming Seismic Activity Atmosphere (IF 2.9) Pub Date : 2024-04-07 Vasilis Tritakis, Janusz Mlynarczyk, Ioannis Contopoulos, Jerzy Kubisz, Vasilis Christofilakis, Giorgos Tatsis, Spyridon K. Chronopoulos, Christos Repapis
We analyzed a large number (77) of low-to-medium-magnitude earthquakes (M3.5–M6.5) that occurred within a period of three years (2020–2022) in the Southern half of Greece in relation to the ELF activity in that region and time period. In most cases, characteristic ELF signals appear up to 20 days before the earthquakes. This observation may add an important new element to the Lithospheric–Atmospheric–Ionospheric

Health Risk Assessment from Exposure to Ambient Volatile Organic Compounds (VOCs) at a Truck Tire Factory in the Yangtze River Delta, China Atmosphere (IF 2.9) Pub Date : 2024-04-08 Songtao Hou, Yalong Wang, Lian Duan, Guangli Xiu
Occupational health risk assessments of exposure to VOCs still need to be extensively studied to improve the safety standards in the industry. Based on the monitoring of organic pollutants at various workstations in a truck tire factory in Jiangsu Province, both semi-quantitative and quantitative health risk assessment methods were employed to assess health risk levels. The findings indicated that

Vegetation–Topographic Landscape and the Influence of Water and Sediment in the Shule River Basin Atmosphere (IF 2.9) Pub Date : 2024-04-08 Jianjun Zeng, Yanqiang Cui
The study of the effect of vegetation cover on water and sediment content is of great significance for the in-depth understanding of ecological and environmental effects in river basins and the formulation of corresponding management measures. Based on the monitoring data of rainfall and runoff of Panjiazhuang and Dangchengwan Hydrologic Stations in Shule River Basin from 2000 to 2020 and the sediment
