Technology adoption in air quality action plans: A policy approach ABSTRACT The air quality actions in India have been in practice since 2005 still however, the number of non-attainment cities have been inceasing significantly. These action plans are multi-disciplinary in nature with several stakeholders required to perform simultaneously. This pose a serious challenge of governance…
Effective calibration of low-cost sensor network using learning techniques ABSTRACT Advances in signal processing algorithms have made it possible employing low-cost sensors (LCS) for air quality monitoring thus offering offering high spatial and temporal resolutions. However, the reliability of LCS data is compromised by environmental effects and drift. This presentation introduces two innovative calibration models,…
Real-time source apportionment for quick air quality actions ABSTRACT Understanding the air pollution sources is important to control and prevent PM2.5 emissions. In previous studies, typical ambient sampling devices collect integrated average samples of long durations and are sent off to the laboratory for a time-consuming and labour-intensive analysis; this invariably provided low temporal resolution…
A novel method for hotspot management – A case study of Local Air Management Plan (LAMP) in Delhi, NCR ABSTRACT Mitigation of hotspots in cities is an integral part of air pollution management. This study combines data from sensors, to supplement existing CAAQMS, along with micro emissions inventory and dispersion modelling to inform targeted grid-based…
Assessment of air pollution induced stress, tolerance and accumulated particulate matter on the selected indigenous plant species in Delhi NCR region ABSTRACT Air pollution is a pressing environmental concern, particularly in densely populated urban areas like the National Capital Region (NCR) of Delhi, India. This research investigates the effects of air pollution on selected indigenous…
Hyperlocal monitoring of air quality to drive evidence-based policy interventions for clean air ABSTRACT Aurassure revolutionizes air quality management through a hyperlocal monitoring approach that has generated nearly 2 million data points across 25+ cities in India. This extensive dataset, focusing on criteria pollutants, greenhouse gases, and noise levels, enables evidence-based policy interventions. By strategically…
Unusual air quality patterns in the era of climate change ABSTRACT It is clear from the emerging recent scientific finding and that while local action has to gather momentum, bigger solutions need regional scale action because air pollution moves across boundaries. In the era of fast changing climate, extreme events are more frequent than ever…
Air pollution characteristics in indoor and outdoor environments ABSTRACT Air pollution is a serious social and environmental problem around the world. Urban air pollution is one of the major issues in India. Air quality in the urban area is deteriorating due to complex interactions between source emissions, poor dispersion conditions, and increased urban warming. In…
Air and noise pollution regulations ABSTRACT The Air (Prevention and Control of Pollution) Act, 1981, and The Noise Pollution (Regulation and Control) Rules, 2000 are the primary legislation addressing air pollution and noise pollution in India. The act empowers the Central Pollution Control Board (CPCB) at the national level and State Pollution Control Boards (SPCBs)…
Measurement of air pollution: Particulate matter ABSTRACT The talk will primarily focus on the various analytical methods available for the assessment of particulate matter in ambient air. Brief details of the physical basis of the methods and the interpretation of the data for different objectives will be discussed in brief. We will also look at…
