Autor: Jong-Uk Park, Jin-Soo Park, Daniel Santana Diaz, Manuel Gebetsberger, Moritz Müller, Lena Shalaby, Martin Tiefengraber, Hyun-Jae Kim, Sang Seo Park, Chang-Keun Song, Sang-Woo Kim
Publikováno v: GIScience & Remote Sensing, Vol 59, Iss 1, Pp 354-373 (2022)
The spatiotemporal inhomogeneity of the total column NO2 amounts (TCN) in the Seoul Metropolitan Area (SMA), Korea, was quantitatively assessed through year-round (October 2019–May 2021) TROPOMI and ground-based Pandora measurements. The average TC

Publikováno v: Atmosphere, Vol 14, Iss 3, p 594 (2023)
To assess the best measures for the improvement of air quality, it is crucial to investigate in situ and columnar pollution levels. In this study, ground-based measurements of nitrogen dioxide (NO2) and ozone (O3) collected in Rome (Italy) between 20
