Abstract. This paper discusses the newly developed Decision Support System version 1.0 (DSS v1.0) for air quality management activities in Delhi, India. In addition to standard air quality forecasts, DSS provides the contribution of Delhi, its surrounding districts, and stubble-burning fires in the neighboring states of Punjab and Haryana to the PM2.5 load in Delhi. DSS also quantifies the effects of local and neighborhood emission-source-level interventions on the pollution load in Delhi. The DSS-simulated Air Quality Index for the post-monsoon and winter seasons of 2021–2022 shows high accur

The impact of air pollution on people and the environment is a severe issue that has recently been the subject of extensive research. This study has looked at the factors that contribute to the seasonal and spatial variability of pollutant concentration over Delhi NCR from 2019 to 2021. Additionally, the causes of changes in air quality during the COVID-19’s lockdown period in 2020 have been discussed, along with comparisons to the pre-lockdown year (2019) and the post-lockdown year (2021). Seven pollutant parameters, viz., (PM2.5, PM10, NOx, CO, SO2, NH3, and O3) were retrieved from the air q

Abstract. Fine particulate matter (PM2.5) and surface ozone (O3) are major air pollutants in megacities such as Delhi, but the design of suitable mitigation strategies is challenging. Some strategies for reducing PM2.5 may have the notable side effect of increasing O3. Here, we demonstrate a numerical framework for investigating the impacts of mitigation strategies on both PM2.5 and O3 in Delhi. We use Gaussian process emulation to generate a computationally efficient surrogate for a regional air quality model (WRF-Chem).

Abstract:

The rich cultural heritage of India has long been a magnet for tourism, with Delhi standing out as a premier destination on the global stage. However, rising air pollution is threatening the city's appeal to international visitors who priorities health and environmental conditions when choosing destinations. This study explores the correlation between the Air Quality Index (AQI) and foreign tourist arrivals (FTA) in Delhi-NCR using secondary data from the Central Pollution Control Board (CPCB) and other government sources from 2015 to 2023. The analysis reveals varying correlation values: peri

AbstractThis study reports a very high-resolution (400 m grid-spacing) operational air quality forecasting system developed to alert residents of Delhi and the National Capital Region (NCR) about forthcoming acute air pollution episodes. Such a high-resolution system has been developed for the first time and is evaluated during October 2019-February 2020. The system assimilates near real-time aerosol observations from in situ and space-borne platform in the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to produce a 72-h forecast daily in a dynamical downscaling frame

Abstract:

Skies over Delhi become blurred and visibility is significantly reduced and the air is hefty and causes a burning sensation in the eyes. As every year in November, a thick blanket of smog veils Delhi and its surrounding National Capital Region-NCR of India, which constitute the world’s most polluted megacity. According to a senior pulmonologist and member of the WHO commission on global air pollution and health, patients experiencing breathing problems increase by 30-40 percent every year during October-November. But Delhi’s smog wasn’t always this bad in early winter; it started only about 10

Abstract:

Indoor air pollution is a matter of serious concern in the mega cities which are grappling with poor air quality. There are very few reports available that discuss the indoor air quality of gaseous ammonia (NH3). This study reports the abundance and risk assessment of NH3 in two distinct urban households of Delhi city during July 2017 to June 2018. Results showed that the NH3 concentrations were consistently higher during entire sampling period at the Dwarka household (DH) site which represented the residential sector having an average value of 102.5 µg/m3, as compared to the Mayapuri househol

Abstract Exposure to airborne microplastics (MPs) is an emerging environmental and public health concern due to their widespread presence and potential toxicity. This study presents the first comprehensive characterization of airborne MPs in Delhi, India, focusing on their seasonal distribution, morphology, chemical composition, and associated health risks. Particulate matter (PM₁₀, PM₂.₅, and PM₁) was collected using active samplers at Lodhi Road during winter (January–March) and summer (April–June) of 2024. Average(± SD) concentrations of MPs were 1.87 ± 0.5 MPs/m3 for PM₁₀, 0.51 ± 0.2 MPs/m

Abstract:

Pollution, the contamination of the environment with harmful materials, affects human health, quality of life, and ecosystem functions. Recently, stubble burning and firecracker usage have drawn attention for their environmental impact, particularly in India’s National Capital Region (NCR): Delhi, where toxic air creates public health emergencies in winter due to inversion, moisture, and poor wind dispersion. Fireworks also cause short-term air quality deterioration by releasing hazardous chemicals and organic pollutants. Ground-level displays have immediate health effects, unlike high-altitud

Abstract:

The harmful effects of air pollution, noise pollution, traffic congestion, and energy consumption can be minimized by more and more use of public transport system. But the service quality is an obstruction in use of public transport. Managing the service quality is crucial and more important factor for increasing the use of public transport. In this paper researchers used SERVQUAL for measuring service quality of one of the modes of public transport. Service quality is an amalgamation of a variety of criteria, among them some vague criteria are difficult to measure. This attribute introduces t

Abstract:

Abstract Deriving hyperlocal information about fine particulate matter (PM2.5) is critical for quantifying exposure disparities and managing air quality at neighborhood scales in cities. Delhi is one of the most polluted megacities in the world, where ground-based monitoring was limited before 2017. Here we estimate ambient PM2.5 exposure at 100-m  100-m spatial resolution for the period 2002-2019 using the random forest model. The model-predicted daily and annual PM2.5 show a 10-fold cross-validation R2 of 0.91and 0.95 and root mean square error of 19.3 and 9.7 g m-3, respectively, against
