Physicochemical characteristics and seasonal variations of PM2.5 in urban, industrial, and suburban areas in South Korea

Asian Journal of Atmospheric Environment, 2023
Among countries that are a part of the Organization for Economic Co-operation and Development, South Korea is the most exposed to PM2.5. Despite the country having implemented various strategies to limit PM2.5 emissions, its concentrations are still high

Ozone exchange within and above an irrigated Californian orchard

Tellus: Series B, Chemical and Physical Meteorology, 2020
In this study, the canopy effects on the vertical ozone exchange within and above Californian orchard are investigated. We examined the comprehensive dataset obtained from the Canopy Horizontal Array Turbulence Study (CHATS).

Simulating the integrated summertime Δ¹⁴CO₂ signature from anthropogenic emissions over Western Europe [PDF]

Atmospheric Chemistry and Physics, 2014
Radiocarbon dioxide (14CO2, reported in Δ14CO2) can be used to determine the fossil fuel CO2 addition to the atmosphere, since fossil fuel CO2 no longer contains any 14C.

Measured Canadian oil sands CO2 emissions are higher than estimates made using internationally recommended methods

Nature Communications, 2019
Evaluating GHG emissions reported to inventories for the oil and gas (O&G) sector is important for countries with resource-based economies. Here the authors provide a top-down assessment of GHG emissions from the Canadian oil sands and find previous ...

Implementation of a dry deposition module (DEPAC v3.11_ext) in a large eddy simulation code (DALES v4.4) [PDF]

Geoscientific Model Development
High-resolution data on reactive nitrogen deposition are needed to inform cost-effective policies. Large eddy simulation models coupled to a dry deposition module present a valuable tool for obtaining these high-resolution data. In this paper we describe

The importance of moist thermodynamics on neutral buoyancy height for plumes from anthropogenic sources [PDF]

Atmospheric Chemistry and Physics
Plume rise plays a critical role in dispersing pollutants emitted from tall stacks, dictating the height reached by buoyant plumes and their subsequent downwind dispersion.
