An inversion of NOx and non-methane volatile organic compound (NMVOC) emissions using satellite observations during the KORUS-AQ campaign and implications for surface ozone over East Asia
Autor: G. Gonzalez Abad, Andrew J. Weinheimer, Armin Wisthaler, Lei Zhu, Jung-Hun Woo, Alan Fried, Amir Hossein Souri, Qiang Zhang, Kelly Chance, Xiong Liu, Donald R. Blake, C. Chan Miller, Caroline R. Nowlan
Publikováno v: Atmospheric Chemistry and Physics. 20:9837-9854
The absence of up-to-date emissions has been a major impediment to accurately simulating aspects of atmospheric chemistry and to precisely quantifying the impact of changes in emissions on air pollution. Hence, a nonlinear joint analytical inversion

Dealing with Spatial Heterogeneity in Pointwise to Gridded Data Comparisons
Autor: Kang Sun, Amir Hossein Souri, Matthew S. Johnson, Kelly Chance, Xiong Liu
Atmospheric modelers and the trace gas retrieval community typically presuppose that pointwise measurements, which roughly represent the element of space, should compare well with satellite (model) pixels (grids). This assumption implies that the fie

Development and Implementation of a Physics‐Based Convective Mixing Scheme in the Community Multiscale Air Quality Modeling Framework
Autor: Jia Jung, Arman Pouyaei, Chul H. Song, Amir Hossein Souri, Yunsoo Choi, Bavand Sadeghi, Chun Zhao
Publikováno v: Journal of Advances in Modeling Earth Systems, Vol 13, Iss 6, Pp n/a-n/a (2021)
To improve the representation of convective mixing of atmospheric pollutants in the presence of clouds, we developed a convection module based on Kain and Fritsch (KF) method and implemented it in the Community Multiscale Air Quality model. The KF‐

The Impact of the Direct Effect of Aerosols on Meteorology and Air Quality Using Aerosol Optical Depth Assimilation During the KORUS‐AQ Campaign
Autor: Amir Hossein Souri, David C. Wong, Jia Jung, Sojin Lee, Yunsoo Choi, Jhoon Kim, Wonbae Jeon
Publikováno v: Journal of Geophysical Research: Atmospheres. 124:8303-8319
To quantify the impact of the direct aerosol effect accurately, this study incorporated the Geostationary Ocean Color Imager (GOCI) aerosol optical depth (AOD) into a coupled meteorology-chemistry model. We designed three model simulations to observe

Characterization of Regional Wind Patterns Using Self-Organizing Maps: Impact on Dallas–Fort Worth Long-Term Ozone Trends
Autor: A. Kotsakis, Wonbae Jeon, Amir Hossein Souri, James Flynn, Yunsoo Choi
Publikováno v: Journal of Applied Meteorology and Climatology. 58:757-772
This study analyzes wind patterns in the Dallas–Fort Worth (DFW) area to gain a clearer understanding of meteorological patterns that have historically led to ozone exceedances in this region. Using a clustering algorithm called “self-organizing

OMI Total Column Water Vapor Version 4 Validation and Applications
Autor: G. Gonzalez Abad, Xiong Liu, Amir Hossein Souri, Kelly Chance, Huiqun Wang
Total Column Water Vapor (TCWV) is important for the weather and climate. TCWV is derived from the OMI visible spectra using the Version 4 retrieval algorithm developed at the Smithsonian Astrophysical Observatory. The algorithm uses a retrieval wind
