Autor: Hyo-Jung Lee, Lim-Seok Chang, Daniel A. Jaffe, Juseon Bak, Xiong Liu, Gonzalo González Abad, Hyun-Young Jo, Yu-Jin Jo, Jae-Bum Lee, Geum-Hee Yang, Jong-Min Kim, Cheol-Hee Kim
Publikováno v: Remote Sensing, Vol 14, Iss 5, p 1285 (2022)
Urban photochemical ozone (O3) formation regimes (NOx- and VOC-limited regimes) at nine megacities in East Asia were diagnosed based on near-surface O3 columns from 900 to 700 hPa, nitrogen dioxide (NO2), and formaldehyde (HCHO), which were inferred

Ozone Continues to Increase in East Asia Despite Decreasing NO2: Causes and Abatements
Autor: Hyo-Jung Lee, Lim-Seok Chang, Daniel A. Jaffe, Juseon Bak, Xiong Liu, Gonzalo González Abad, Hyun-Young Jo, Yu-Jin Jo, Jae-Bum Lee, Cheol-Hee Kim
Publikováno v: Remote Sensing, Vol 13, Iss 11, p 2177 (2021)
Space-borne ozone (O3) measurements have indicated consistent positive trends across the entire Asia–Pacific region despite the considerable reduction of NOx since 2000s. The rate of increase in O3 derived from lower free tropospheric column measur

Distinct Meteorological Mode associated with High PM2.5 Episodes in Seoul, South Korea
Autor: Daniel Choi, Hyo-Jung Lee, Lim-Seok Chang, Hyun-Young Jo, Yu-Jin Jo, Shin-Young Park, Geum-Hee Yang, Cheol-Hee Kim
Publikováno v: Journal of Applied Meteorology and Climatology.
In this study, high particulate matter (PM2.5) pollution episodes were examined in Seoul, the capital city of South Korea, which, based on the episode characteristics, were influenced by a distinct meteorological mode, long-range transport (LRT), fro

Diurnal variation of columnar and surface in-situ HCHO over Seoul in SIJAQ 202
Autor: Lim-Seok chang, Donghee Kim, Min-Suk Bae, Rokjin Park
The GEMS capability to monitor daily changes in key air pollutants was examined with ground-based remote sensing in the SIJAQ 2021 campaign (October 16 - November 11, 2021). In particular, HCHO, a type of GEMS primary product, plays an important role
