Impact of a First-Order Riparian Zone on Nitrogen Removal and Export from an Agricultural Ecosystem

open access: yesThe Scientific World Journal, 2001
Riparian zones are reputed to be effective at preventing export of agricultural groundwater nitrogen (N) from local ecosystems. This is one impetus behind riparian zone regulations and initiatives. However, riparian zone function can vary under different

Improvement of stomatal resistance and photosynthesis mechanism of Noah-MP-WDDM (v1.42) in simulation of NO2 dry deposition velocity in forests [PDF]

open access: yesGeoscientific Model Development, 2022
Rapid urbanisation and economic development in China have led to a dramatic increase in nitrogen oxide (NO2) emissions, causing serious atmospheric nitrogen pollution and relatively high levels of nitrogen deposition.

Long-term changes of rice yield loss estimated with AOT40 and M7 metrics using comprehensive ozone and rice cultivation data over South Korea

open access: yesAsian Journal of Atmospheric Environment, 2023
This study examines the change in rice yield due to ozone exposure in South Korea using extended air quality monitoring data from 2000 onwards. Notably, the maximum daily 8-h average O3 (MDA8O3) showed a substantial annual increase of 1 part per billion ...

Development of a deep neural network for predicting 6 h average PM2.5 concentrations up to 2 subsequent days using various training data [PDF]

open access: yesGeoscientific Model Development, 2022
Despite recent progress of numerical air quality models, accurate prediction of fine particulate matter (PM2.5) is still challenging because of uncertainties in physical and chemical parameterizations, meteorological data, and emission inventory ...

On the Relation between Discounting of Climate Change and Edgeworth-Pareto Substitutability [PDF]

open access: yes, 2009
To justify substantial carbon emission reductions, recent literature on cost-benefit analysis of climate change suggests discounting environmental quality at a lower discount rate than the standard consumption discount rate.

Crop Residue Burning in Northeast China and Its Impact on PM2.5 Concentrations in South Korea

open access: yesAtmosphere, 2021
The impact of crop residue burning in northeastern China on South Korean PM2.5 concentrations was assessed via weather conditions, air quality modeling (AQM), and PM2.5 composition data during two cases exceeding 35 µg·m−3 in November 2015.

Fate and transport in environmental quality

open access: yesJournal of Environmental Quality, 2021
AbstractChanges in pollutant concentrations in environmental media occur both from pollutant transport in water or air and from local processes, such as adsorption, degradation, precipitation, straining, and so on. The terms “fate and transport” and “transport and fate” reflect the coupling of moving with the carrier media and biogeochemical processes ...
