The objectives of the Winter Fog Experiment (WIFEX) over Indo-Gangetic Plains India are to develop better now-casting and forecasting winter fog on various time-and spatial scales.Maximum occurrence northwest is about 48 days (visibility <1000 m) per year, it occurs mostly during December-February time-period.The physical chemical characteristics fog, meteorological factors responsible for its genesis, sustenance, intensity dissipation poorly understood.Improved understanding above aspects...
Accurate emission inventories serve as critical inputs for air quality and climate models but are poorly constrained over India. We present a new municipal open waste burning inventory from India (OWBEII), at resolution of 0.1° × 0.1°. Out the 216 (201–232) Tg y–1 produced in year 2015, 68 (45–105) was burned open. To determine emissions burning, factors 59 non-methane volatile organic compounds (NMVOCs), CH4, CO2, CO, NOx were measured garbage fires rural urban sites The NMVOC 1.4–2...
Abstract. In complex atmospheric emission environments such as urban agglomerates, multiple sources control the ambient chemical composition driving air quality and regional climate. contrast to pristine sites, where reliance on single or a few tracers is often adequate for resolving pollution plumes source influences, comprehensive fingerprinting of using non-methane hydrocarbons (NMHCs) identification suitable tracer molecules ratios becomes necessary. Here, we characterise present...
Traffic emissions are a major source of air pollution and associated damage to human health in India. Many the Indian metro cities urgently require cleaner transportation technologies ensure air. Here, using newly compiled spatially disaggregated, gridded, high-resolution (0.1° × 0.1°) road transport emission inventory for India 2030 (RTEII) 74 speciated VOCs, CO, SO2, NOx, NH3, CH4, CO2, BC, OC PM2.5 from varied fuels vehicle that currently use India, we investigated changes response...
This paper provides an overview of the INGENIOUS (UnderstandING sourcEs, traNsformations and fates IndOor air pollUtantS) project, aiming to better understand pollution in homes. Although our homes are microenvironment which we spend most time, know relatively little about sources, transformation processes indoor pollutants, or exposure them. aims address this knowledge gap by delivering: emissions inventory for UK homes; comprehensive pollutant measurements 310 Bradford using a combination...
In developed countries, people spend nearly 90% of their time indoors, where activities such as cooking and cleaning are significant sources air pollution, with consequent impacts on occupant health. Volatile organic compounds (VOCs), emitted can also escape into the urban outdoor environment contribute to secondary e.g. via production ozone particulate matter formation. This comes at a when successful regulation has led gradual decreases in emission from some traditional traffic. Despite...
We studied the impact of odd-even traffic rule (implemented in Delhi during 1-15 January 2016) on primary emissions using measurements 13 volatile organic compounds, carbon monoxide, dioxide and methane at a strategic arterial road (28.57N, 77.11E, 220 m amsl).Whole air samples (n = 27) were collected active (OA) inactive (OI) days, analysed IISER Mohali Atmospheric Chemistry Facility.The average mass concentration ranking toluene/benzene ratio characteristic both OA OI samples, with...
Abstract. Biogenic volatile organic compounds exert a strong influence on regional air quality and climate through their roles in the chemical formation of ozone fine-mode aerosol. Dimethyl sulfide (DMS), particular, can also impact cloud radiative budget as it produces sulfate aerosols upon atmospheric oxidation. Recent studies have reported DMS emissions from terrestrial sources; however, magnitudes been too low to account for observed ecosystem-scale emission fluxes. Big-leaf mahogany...
In today's competitive market, maximizing Customer Lifetime Value (CLV) is essential for sustaining growth and profitability. Effective onboarding renewal management are critical strategies in achieving this goal. This paper explores the interplay between customer experiences processes, emphasizing their role fostering long-term relationships enhancing satisfaction. A comprehensive program not only educates customers about product functionalities but also helps to set expectations establish...
21 of 30 most polluted cities for particulate matter (PM2.5) are in India, yet the distribution, identity and emissions volatile organic compounds (VOCs) from traffic, which PM2.5 ozone precursors, remain unknown. Here, we measured emission factors (EFs) 74 VOCs a range Indian vehicle-technology fuel types. When combined with 0.1 ° × spatially resolved activity data year 2015, toluene (137 ± 39 Gg yr1), isopentane (111 38 Ggyr−1), acetaldehyde (41 6 Ggyr−1) were top 3-VOC emissions....
As the wealth of evidence grows as to negative impact indoor air quality on human health, it has become increasingly urgent investigate and characterise sources pollution within home. Fine particulate matter with a diameter 2.5 µm or less (PM2.5) is key cause for concern, cooking known be one most significant domestic PM2.5. In this study, aim was demonstrate efficacy combining experimental techniques cutting-edge High-Performance Computing (HPC) dispersion PM2.5 during stir-frying kitchen...

Emission rates for volatile organic compounds (VOCs) have been quantified from frying, spice and herb cooking, cooking a chicken curry, using real-time selected-ion flow-tube mass spectrometry (SIFT-MS) controlled, laboratory-based experiments in semi-realistic kitchen. Emissions 7 different oils were investigated during the frying of wheat flatbread (puri). These emissions dominated by ethanol, octane, nonane variety aldehydes, including acetaldehyde, heptenal hexanal, average concentration...
