Elucidation of spatial disparities of factors that affect air pollutant concentrations in industrial regions at a continental level

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
Industrial regions and relevant infrastructures are known to contribute to air pollutant emissions; thus, a detailed investigation of the air pollutant concentrations of a region based on specific land uses, with spatial reasoning, can support smart ...

National Emissions of Greenhouse Gases and Air Pollutants from Commercial Aircraft in the Troposphere over South Korea

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2014
This study estimated greenhouse gas (GHG) and air pollutant emissions from aircraft in the troposphere (aircraft cruise altitudes, 1 - 12 km) over South Korea over a two-year period (2009 - 2010) using an activity-based (Landing and Take-Off (LTO) cycle)

Non-linearity of secondary pollutant formation estimated from emissions data and measured precursor-secondary pollutant relationships

open access: yesnpj Climate and Atmospheric Science, 2022
In order to predict the impacts of reductions in air pollutant emissions, it is important to know whether secondary pollutant concentrations will decline in direct proportion to the reduction in their precursor, referred to as linearity.

A Comprehensive Approach to Establish the Impact of Worksites Air Emissions

open access: yesChemical Engineering Transactions, 2022
Worksite activities are time-limited events associated with continuous releases of airborne pollutants, such as carbon monoxide, particulate matter, and NOx, and they impact potentially vast areas.

Exploring Deep Learning for Air Pollutant Emission Estimation [PDF]

open access: yesGeoscientific Model Development, 2021
Abstract. The inaccuracy of anthropogenic emission inventory on a high-resolution scale due to insufficient basic data is one of the major reasons for the deviation between air quality model and observation results. A bottom-up approach, as a typical emission inventory estimation approach, requires a lot of human labor and material resources, and a top-

Low carbon optimal operation of integrated energy systems considering air pollution emissions

open access: yesEnergy Reports, 2023
To reduce carbon, sulfur dioxide (SO2) and nitrogen oxide (NOX) emissions from the integrated energy system (IES), a low carbon optimization strategy for the IES is proposed, taking into account carbon, SO2 and NOXemissions. Firstly, hydrogen production,
