Journal ArticleDOI
Simultaneous satellite observations of IO and BrO over Antarctica
Anja Schönhardt,M. Begoin,Andreas Richter,Folkard Wittrock,Lars Kaleschke,J. C. Gómez Martín,John P. Burrows +6 more
TL;DR: In this article, satellite observations of iodine monoxide and bromine monoxide (BrO) and compared to the distributions of BrO are presented and the influence of the IO air mass factor and the IO absorption cross section temperature dependence on the absolute vertical columns are discussed.
Journal ArticleDOI
An improved glyoxal retrieval from OMI measurements
Leonardo M. A. Alvarado,Andreas Richter,Mihalis Vrekoussis,Folkard Wittrock,Andreas Hilboll,Stefan F. Schreier,John P. Burrows +6 more
TL;DR: In this paper, the authors developed an improved retrieval for glyoxal (CHOCHO) from measurements by the OMI instrument and determined a fitting window and a polynomial degree.
Journal ArticleDOI
Enhanced trans-Himalaya pollution transport to the Tibetan Plateau by cut-off low systems

TL;DR: In this article, the authors used short-lived reactive aromatics as proxies to diagnose transport of pollutants to Tibet using a regional chemistry and transport model and found that top-down emissions constrained by satellite observations of glyoxal are a factor of 2-6 higher than the a priori emissions over the industrialized Indo-Gangetic Plain.
Journal ArticleDOI
Glyoxal observations in the global marine boundary layer

TL;DR: The results reported in this paper support previous suggestions that the currently known sources of glyoxal are insufficient to explain the average MBL concentrations, which suggests that there is an additional missing source, more than a magnitude larger than currently known source, which is necessary to account for the observed atmospheric levels of glyoxide.
