Hydroclimate Changes Based on Testate Amoebae in the Greater Khingan Mountains’ Peatland (NE China) during the Last Millennium Atmosphere (IF 2.9) Pub Date : 2024-03-01 Xiao Li, Dongxue Han, Jinxin Cong, Chuanyu Gao, Guoping Wang
The driving force of climate change in the monsoon margin is complex, making it a key area for regional and global climate change research. Palaeohydrological studies in the monsoon margin have increased the resolution of research in the long term, transitioning from qualitative to quantitative studies to comprehend climate change processes, patterns, and mechanisms. Testate amoebae (TA) in peat sediments

Factors Influencing the Concentration of Negative Air Ions in Urban Forests of the Zhuyu Bay Scenic Area in Yangzhou, China Atmosphere (IF 2.9) Pub Date : 2024-03-02 Xin Wan, Runyang Zhou, Liwen Li, Can Yang, Jingwei Lian, Jiaojiao Zhang, Sian Liu, Wei Xing, Yingdan Yuan
Negative air ions (NAIs) are an important indicator of air cleanliness in an area, and play a vital role in promoting the psychological and physiological functions of the human body. However, there are few studies regarding the relationship between NAI concentration and various environmental factors in urban forests. Therefore, we established an observation point in the Zhuyu Bay Scenic Area in Yangzhou

Cloud Characteristics during Intense Cold Air Outbreaks over the Barents Sea Based on Satellite Data Atmosphere (IF 2.9) Pub Date : 2024-03-02 Alexandra Narizhnaya, Alexander Chernokulsky
The Arctic experiences remarkable changes in environmental parameters that affect fluctuations in the surface energy budget, including radiation and sensible and latent heat fluxes. Cold air masses and cloud transformations during marine cold air outbreaks (MCAOs) substantially influence the radiative fluxes, thereby shaping the link between large-scale dynamics, sea ice conditions, and the surface

Climate Change Impacts on the Energy System of a Climate-Vulnerable Mediterranean Country (Greece) Atmosphere (IF 2.9) Pub Date : 2024-02-27 Elena Georgopoulou, Sevastianos Mirasgedis, Yannis Sarafidis, Christos Giannakopoulos, Konstantinos V. Varotsos, Nikos Gakis
Climate change is expected to significantly affect countries in Southern Europe and the Mediterranean Basin, causing higher-than-average temperature increases, considerable reductions in rainfall and water runoff, and extreme events such as heatwaves. These pose severe threats to local energy systems, requiring a reliable and quantitative risk analysis. A methodological approach is thus proposed which

Resilience Assessment and Improvement Strategies for Urban Haze Disasters Based on Resident Activity Characteristics: A Case Study of Gaoyou, China Atmosphere (IF 2.9) Pub Date : 2024-02-27 Yang Cao, Tingting Yang, Hao Wu, Shuqi Yan, Huadong Yang, Chengying Zhu, Yan Liu
The popularisation of mobile information technology has provided access to the living habits and activity trajectories of residents and enabled the accurate measurement of the impact of urban haze disasters on residents’ lives, supporting urban haze risk response. Using the main urban area of Gaoyou City as a case study, this study identifies the spatial range and trajectory characteristics of the

Using Diverse Data Sources to Impute Missing Air Quality Data Collected in a Resource-Limited Setting Atmosphere (IF 2.9) Pub Date : 2024-02-28 Moses Mogakolodi Kebalepile, Loveness Nyaradzo Dzikiti, Kuku Voyi
The sustainable operation of ambient air quality monitoring stations in developing countries is not always possible. Intermittent failures and breakdowns at air quality monitoring stations often affect the continuous measurement of data as required. These failures and breakdowns result in missing data. This study aimed to impute NO2, SO2, O3, and PM 10 to produce complete data sets of daily average

Evaluation of Surrogate Aerosol Experiments to Predict Spreading and Removal of Virus-Laden Aerosols Atmosphere (IF 2.9) Pub Date : 2024-02-29 Janis Beimdiek, Hans-Joachim Schmid
Estimating the infection risks of indoor environments comprises the assessment of the behavior of virus-laden aerosols, i.e., their spreading, mixing, removal by air purifiers, etc. A promising experimental approach is based on using non-hazardous surrogate aerosols of a similar size, e.g., salt particles, to mimic virus aerosol behavior. This manuscript addresses the issue of how a successful transfer

Assessing the Performance of Water Vapor Products from ERA5 and MERRA-2 during Heavy Rainfall in the Guangxi Region of China Atmosphere (IF 2.9) Pub Date : 2024-02-29 Ning Huang, Shiyang Fu, Biyan Chen, Liangke Huang, Wenping Jin
Precipitable water vapor (PWV) is a crucial factor in regulating the Earth’s climate. Moreover, it demonstrates a robust correlation with precipitation. Situated in a region known for the generation and development of tropical cyclones, Guangxi in China is highly susceptible to floods triggered via intense rainfall. The atmospheric water vapor in this area displays prominent spatiotemporal features
