“…Studies in the past have reported adverse health issues such as premature mortality, exacerbate bronchitis, asthma attacks, other respiratory symptoms, cardiovascular attacks, etc., if humans are exposed to the sudden increase of particulate matters (Wilson and Suh, 1997;Bell et al, 2007;Kim et al, 2015;Kumar Rai, 2015;Abel et al 2018;Chhabra et al, 2020 Another direct impact of the dust storm can be seen in the atmospheric boundary layer over this region. Backscatter from the aerosols has been continuously recorded by the Ceilometer stationed at Physical Research Laboratory, Ahmedabad.…”

The present study focuses on investigating the impacts of a sudden dust storm on the atmospheric boundary layer (ABL) over Ahmedabad (23.02°N, 72.57°E), an urban site located in the western region of India. The accumulation of dust in the atmosphere during the dust storm, originating from the Thar Desert in Rajasthan, led to the decrease in surface temperature as a consequence of dust-radiation interaction. Ambient particulate matter data obtained from Air Quality (AQ) station at Ahmedabad showed a spike of 118.5% and 44.5% in PM10 and PM2.5 concentrations, respectively during the event in comparison to the previous control day. Sudden exposure to an anomalous increase in particulate aerosols may cause severe impacts on human health. These surface forcing have been reflected in the stable nocturnal ABL. Backscatter signals recorded by ground-based Ceilometer Lidar at Physical Research Laboratory (PRL), showed that ABL was shallow and collapsed during the dust storm episode. Turbulence was detected in the ABL during the event which further assisted in the vertical mixing of dust aerosols in the ABL. These aerosols got trapped within the residual layer, preventing further percolation in the free atmosphere. Such sub-grid scale changes in the ABL during the dust storm were not reflected in the boundary layer height (BLH) obtained from the ERA-5 reanalysis dataset. A significant association between the ABL and the local radiative budget has been found. It has been substantiated by Coupled Ocean-Atmosphere Radiative Transfer Model (COART) simulations that showed a cooling of the surface. Thus, this study is important as it can be taken as feedback to improve local climate models with respect to dust storm meteorology.

“…In this study we used meteorological parameters and particulate matter data from the air quality monitoring station at the Space Applications Centre, Ahmedabad, under the Ministry of Earth Sciences, System of Air Quality and Weather Forecasting and Research (SAFAR) programme of the Government of India. This SAFAR station is located on the outskirts of Ahmedabad and is 8.9 km from the boundary layer measurement site (Chhabra et al, 2020 ). It is represented as Station 2, and Station 1 is the ceilometer at the Physical Research Laboratory (PRL).…”

The government of India imposed a nationwide lockdown to tackle the outbreak of COVID-19 in 2020. This period witnessed record low anthropogenic activity, which had severe socio-economic impacts but also had orthogonal effects on the ambient air quality of the atmosphere. This study focuses on the variations in the atmospheric boundary layer (ABL) over a western Indian urban region in the light of COVID-19. Continuous backscatter recorded by a ceilometer, stationed at Ahmedabad, was used in this study to monitor the ABL during the national lockdown (NLD) in 2020 and state restrictions in 2021, and compared with the control year of 2019. In parallel, improvement in air quality during the NLD was observed by the SAFAR air quality station at Ahmedabad, with decreased particulate matter concentrations. The ground-based observations were substantiated by the ERA5 reanalysis dataset. A decline in the ABL height was recorded during the NLD, which showed improvement in 2021 but which was shy of the ABL in 2019. This was correlated with rain events during the observational period, recorded by an automatic weather station.

“…Hence, it is crucial to monitor short-term events to identify dates and spatial patterns of pollutant sources for environmental management and risk assessment (Chen et al, 2022;Chhabra et al, 2020). Although technological sensors provide detailed information on PM concentration over time, complementarily, environmental networks using biological indicators can also provide particle pollution data recorded over months, years, or seasons (McIntosh et al, 2007;Paoli et al, 2017;Castañeda Miranda et al, 2020;Chaparro et al, 2024).…”

The high concentrations of particulate matter (PM) in the atmosphere have adverse effects on both the environment and human health, as well as on urban and faunal biodiversity. Short-term events, such as the burning of fireworks, attributable to human activity, result in a significant and rapid increase in PM concentration levels within the atmosphere. We present findings derived from observations made using low-cost PM sensors deployed as part of the Environmental Monitoring Network in Querétaro, Mexico. These sensors utilize the Environmental Geo Monitoring Stations (EMGA) device, developed by the Institute of Geosciences at UNAM. The observation period spanned from December 10, 2023, to January 10, 2024, encompassed the Christmas and New Year holidays, and focused on PM2.5 concentrations, and a comparison with a similar period from February 10, 2024, to March 10, 2024, considered a typical activity period in the area. The results reveal a substantial increase in PM2.5 concentrations over time and spatial distribution during this period, with notable increases observed during the festive season. Specifically, prolonged periods exceeding up to 6 hours were noted on festivities dates. This research offers insight into the effects, trends, and spatial-temporal distribution of pollutants within the city of Queretaro, which may be used as a reference for other cities around the world. Furthermore, a comparison between PM2.5 data recorded by the EMGA devices and infrasound data was conducted complementarity to explore potential correlations between these two types of data.
