Radiative effect of atmospheric Brown clouds over the Indo-Gangetic plain

Atmospheric brown clouds (ABCs) are widespread hazy accumulation of particles and gases dominant with absorbing nature impacting the air quality, hydrology and climate. The Indo-Gangetic plain (IGP) being an ABCs hotspots is prone to extreme pollution episodes due to anthropogenic activities. However, there is a scarcity of studies that specifically compare episodes of absorbing aerosols (ABCs) and comparatively non-absorbing aerosols (non-ABCs) along with their respective radiative impacts over the IGP. Here, we have used ground-based remote-sensors’ retrieved datasets from AErosol RObotic NETwork (AERONET) to study spatio-temporal variation of ABCs’ frequency and associated radiative properties across the IGP region during 2001–2019. The shortwave aerosol radiative effect (ARE) during ABC and non-ABC episodes is estimated using Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART) model. Our results show significant spatial variability in the frequency of ABC episodes across the IGP stations with ∼17 ± 5%, ∼19 ± 11% and ∼18 ± 13% average occurrence during winter, pre-monsoon and post-monsoon seasons, respectively. ARE estimations show enhanced surface dimming (ARESRF) and atmospheric warming (AREATM) during ABC episodes as compared to non-ABC episodes. A general increasing trend for ARE is observed as we move from west to east across the IGP due to the meteorological and geographical variations in the region. Our results show day-time averaged ARESRF varying between −142.46 ± 25.13 and −56.66 ± 6.88 W/m2 while AREATM ranging from 58.07 ± 2.58 to 132.69 ± 7.43 W/m2 for ABC episodes. Though ABC episodes show lower aerosol loading as compared to non-ABC episodes in our study, we found higher atmospheric heating during ABC episodes mainly due to distinct chemical composition (lower single scattering albedo) of absorbing aerosols. The upper bound of the difference between atmospheric heating rate during ABC and non-ABC episodes is found to be 0.48 ± 0.27 K/day.

Environmental factors and stroke: Risk and prevention

Stroke is a leading cause of death and adult disability globally. In addition to traditional risk factors, environmental risk factors have emerged over the recent past and are becoming increasingly important. The disproportionate rise of stroke incidence in low- and middle-income countries has been attributed, at least in part, to environmental factors. This narrative review provides details on the interplay between the environment and health generally and stroke specifically, covering topics including air pollution, atmospheric brown clouds, desert dust storms, giant wildfires, chemical contamination, biological aggressors, urbanization, and climate change. It also covers some beneficial environmental effects such as can be harnessed from the exposure to green spaces. It concludes with a summary of pragmatic actions that can be taken to help address some of these challenges at individual, community, and political advocacy levels.

Development of emission reduction measures of trace gas emissions from coal-fired power plants in Indonesia

Most of Indonesia’s electricity demand is supplied by coal fired power plants (CFPPs) which can potentially emit huge amounts of air pollutant gases such as NOx and SO2 gas. The country has committed to reduce Greenhouse Gases (GHGs) emission by 2030 through Nationally Determined Contributions but some emission reduction measures may also reduce air pollutant gases. Flue Gas Desulfurization (FGD) and Atmospheric Fluidized Bed Combustion (AFBC) are the leading control technologies for reducing SO2 and NOx emissions that can be installed in the CFPPs. This study aims to determine the pollution load of SO2 and NOx gases in 2030 generated from CFPPs operation with (reduction scenario) and without FGD and AFCB control technology (business as usual (BAU)). The gas pollution load was calculated using the Atmospheric Brown Clouds- Emissions Inventory Manual (ABC-EIM) procedure. Based on the BAU scenario, the emission load accounted of 1,440,192 tons/year for NOx and 613,121 tons/year for SO2 in 2030. After implementing the control technology scenarios in 2030, the NOx emission load is projected to decrease to 579,610 tons/year, and the SO2 emission load decrease to 77,920 tons/year. The application of AFBC and FGD control technologies can potentially reduce NOx and SO2 emissions load from CFPPs operation in 2030 thus it can help to improve air quality in the future.

Development of emission reduction measures of particulate matter emitted from coal fired power plants in Indonesia

Currently, Indonesia has committed to achieve Net Zero Emissions (NZE) efforts on their Nationally Determined Contribution (NDCs) and at the same time focusing on air pollution abatement. One of the dominant emissions sources of particulate matter as well as Greenhouse Gases (GHGs) is from coal fired power plants. It contributes 50% to the total energy consumption in power generation, therefore the major power plant in Indonesia. Therefore, efforts to reduce GHGs and particulate emissions are needed to achieve the NZE target as well as to improve air quality. The research objective is to determine the particulate pollution load based on the Business as Usual (BaU) scenario and also under the emission reduction scenario for the year of 2030. Particulate pollution load was calculated using the emissions inventory methodology described in the brown cloud atmosphere workbook (ABC-EIM). Particulate emission reduction scenarios were developed using the assumption of full installation of Electrostatic Precipitator (ESP) technology to control PM emission. In 2030, the emission reductions PM10, PM2.5, Black Carbon (BC), and Organic Carbon (OC) are 57,854 ton/year, 57,854 ton/year, 432 ton/year, and 1,723 ton/year.

Especially after the COVID-19 pandemic, when many people temporarily lost their ability to detect smell (and the closely connected sense of taste), this book’s topic is an impetus for important scientific exploration. This book attempts to answer three main questions: How does the brain make sense of scents? What are the perceptual dimensions of smell? What are the epistemic, empirical, and social factors that define ongoing science (in comparison with the philosophical study of historical episodes)? I have a keen memory of as a child smelling the rising aroma of coffee roasting at my uncle’s farm. It is with great fondness that I recall that wonderful imagery every time...

Assessing the Impact of Self‐Lofting on Increasing the Altitude of Black Carbon in a Global Climate Model

AbstractBlack carbon (BC) absorbs solar radiation, increasing the buoyancy and vertical ascent of absorbing aerosol in the atmosphere. This self‐lofting process has been observed for individual plumes in the troposphere and lower stratosphere but here we show it occurring at broader scales through enhanced large‐scale ascent over BC‐rich regions. This is demonstrated in a pair of simulation using the UKESM1 Earth‐System model where BC aerosols were modeled either with or without the ability to absorb radiation. With absorption included the annual global mean concentration of BC in the upper troposphere and lower stratosphere (8–22 km) rose by up to 50% and the column loading over some remote oceanic regions more than doubled. The increase in aerosol height was particularly notable over the southeast Atlantic where biomass burning aerosol from Africa was elevated up to 1 km higher when their absorption was included. Similar effects were seen over the Arctic where the absorbing haze was transported in at higher levels and surface concentrations were halved. The absorption by BC also increased ascent over southern Asia, which tended to thicken the Asian brown cloud during the dry season but in the wet season enhancing ascent promoted deep convection and had the tendency to deplete the aerosol through wash‐out. We conclude that representing aerosol absorption accurately is important in simulating the vertical distribution, transport and abundance of aerosol in the Earth‐system that will affect their interactions with climate.

Investigatory Studies on Pattern in Enhancement in Fine Particulate Matter in the Delhi during winters

Smog is a harmful mixture of fog, smoke, dust and air pollutants such as nitrogen oxides, volatile organic compounds etc. Ground ozone can cause distressing health effect. Smog is a complex atmospheric pollutant mixture consisting of ozone, a pollutant with adverse effects on human health, vegetation, and materials; other eye-irritant and phytotoxic pollutants (such as aldehydes and peroxyacetyl nitrates); nitrogen dioxide (cause of the “whiskey-brown” color in the Los-Angeles atmosphere); and fine particles that cause adverse health effects, reduce visibility, and cause the “brown cloud” phenomenon. Photochemical smog is produced by vehicular emission mainly. Here we are discussing chemistry of formation of PAN (Peroxyacetyl nitrate), its impact environment & human health.

Climate Ghosts focuses on three “ghost species”—groups of organisms that have declined in numbers or been displaced from their native habitats, but not gone completely extinct—loons, caribou, and lake sturgeon. Readers will learn about the historical events that led to the decline of these species, efforts to restore their habitats and populations, and the cultural and religious significance of these species to Indigenous communities in the Great Lakes region. Throughout the book, Langston emphasizes that “restorationists don’t need to invent a new philosophy; they need to learn from Indigenous communities who have already articulated relational ways of knowing” (p. 5). All three examples illustrate how European settlers and industrialism impacted the organisms. The ecosystem changed, the land and its populations mismanaged. I was...

An innovative passive sampler to reveal the high contribution of biomass burning to black carbon over Indo-China Peninsula: Radiocarbon constraints

Black carbon (BC) is an important component of the brown clouds, contributing to climate and health effects of air pollution. In this work, we developed a new method for measuring BC concentrations and its radiocarbon isotope (14C) using quartz wool disk passive air samplers (Pas-QW). A field calibration study was conducted at two sampling sites (Guangzhou and Yantai), using an improved thermal/optical method to measure BC. Uptake profiles of Pas-QW were linear over the 77 days that the samplers were deployed, and the average sampling rate of BC measured was 1.1 ± 0.2 m3/day. The method was found to be reproducible with coefficients of variation as low as 17% for BC measured in ambient passive samples. Furthermore, passive sampling was carried out at six sites in the Indo-China Peninsula (ICP) from January to April and June to September of 2016. The high BC concentrations and the high fraction of modern carbon (fM) values emphasizes that ICP is still dominated by biomass burning emissions (residential cooking and agricultural burning), both in dry and wet seasons. This study provides a proof concept and methodology for the application of Pas-QW to cost-effectively expand measurements of BC at the global scale.

An asteroid, 7.5 miles in diameter, traveling at over 44,000 miles per hour, struck the Earth along the northern coast of the Yucatán Peninsula. The impact caused earthquakes, tsunamis, a global infrared heat pulse hotter than an oven on broil, and global firestorms that pumped soot into the atmosphere blocking out a significant amount of sunlight for an extended period. In The Last Days of the Dinosaurs, science writer Riley Black employs her extensive knowledge of paleontology and vivid imagination to take the reader on a tour of the Cretaceous ecosystem around Hell Creek in Montana at a time just before the impact, then describes the likely aftereffects.

Assessment greenhouse gas emissions on households in Can Tho city

This study investigated household greenhouse gas (GHG) emissions in Ninh Kieu, Cai Rang and Binh Thuy districts in Can Tho city. The calculated emissions were based on the Intergovernmental Panel on Atmospheric Brown Cloud Emission Inventory Manual - ABC EIM (2013) for the 3 gases of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Data collection is through the interviewing of 565 households including direct emission sources (gas, coal, firewood burning activities) and indirect emission sources (electricity consumption and domestic solid waste burning). The results found that in the year 2019, the total GHG emissions in the three districts was 1,008,197.82 tons CO2eq/year, in which CO2accounted for the highest proportion with 988,716.68 tons/year (98.07%), with both CH4 and N2O accounting for a very low proportion with about 1.88 and 0.05% respectively. Among the districts, Ninh Kieu contributed the highest proportion to emission at 59.43%, next to Cai Rang at 21.69% and the final in Binh Thuy at 18.88%. In addition, it was revealed that indirect emission sources of 1.4 times higher than direct emission sources in which Ninh Kieu district has the highest emission and higher than Cai Rang and Binh Thuy districts at 6.4 to 7.6 times, respectively. The research outcomes will be supported to the policy makers in greenhouse gas emission mitigation scenario development and serve as a basis for formulating emission reduction strategies of the city.

He was a brilliant researcher and devoted scientific communicator, attempting to convey the relevance of contemporary findings to people’s lives. Unfortunately, Weinberg is most known for a single quote: “The more the universe seems comprehensible, the more it also seems pointless.” From the example of Weinberg’s life, it’s quite clear that he felt our existence had meaning. The ways we treat each other matter. Weinberg strove to live ethically, even in the face of intense criticism. Still, it’s perilously easy for someone with a materialistic view of the universe to sink into despair. I could go on about this, but surely I don’t need to: as we slump through our third year of global pandemic, probably most of us are far too familiar with despair. Lulu...
