Application of Chemical Ionization Mass Spectrometry in Airborne SO2 Observation on Hanseo Beechcraft 1900 D

open access: yesAsian Journal of Atmospheric Environment, 2020
As the observational constraints of SO2 become a limiting factor for emission inventory and regional and global transport model validations, we present an airborne SO2 observational suite integrated on Beechcraft 1900D (B1900D) operated by Hanseo ...

The use of hierarchical clustering for the design of optimized monitoring networks [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Associativity analysis is a powerful tool to deal with large-scale datasets by clustering the data on the basis of (dis)similarity and can be used to assess the efficacy and design of air quality monitoring networks.

Mesoscale modeling of lake effect snow over Lake Erie – sensitivity to convection, microphysics and the water temperature [PDF]

open access: yesAdvances in Science and Research, 2010
Lake effect snow is a shallow convection phenomenon during cold air advection over a relatively warm lake. A severe case of lake effect snow over Lake Erie on 24 December 2001 was studied with the MM5 and WRF mesoscale models.

An Efficient Parameterization for Surface Shortwave 3D Radiative Effects in Large‐Eddy Simulations of Shallow Cumulus Clouds

open access: yesJournal of Advances in Modeling Earth Systems, 2023
Most atmospheric models consider radiative transfer only in the vertical direction (1D), as 3D radiative transfer calculations are too costly. Thereby, horizontal transfer of radiation is omitted, resulting in incorrect surface radiation fields.

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.
