Journal ArticleDOI
Global budgets of atmospheric glyoxal and methylglyoxal, and implications for formation of secondary organic aerosols
Tzung-May Fu,Tzung-May Fu,Daniel J. Jacob,Folkard Wittrock,John P. Burrows,Mihalis Vrekoussis,Daven K. Henze +6 more
TL;DR: In this paper, a detailed simulation of glyoxal and methylglyoxal in the GEOS-Chem global 3-D chemical transport model including the best knowledge of source and sink processes was conducted.
Journal ArticleDOI
GOME observations of tropospheric BrO in northern hemispheric spring and summer 1997
TL;DR: In this paper, a large and persistent event has been reported over the Hudson Bay area and parts of the Canadian Arctic, which can only be explained by a large local source of bromine.
Journal ArticleDOI
Simultaneous global observations of glyoxal and formaldehyde from space
Folkard Wittrock,Andreas Richter,Hilke Oetjen,John P. Burrows,Maria Kanakidou,Stelios Myriokefalitakis,Rainer Volkamer,Steffen Beirle,Ulrich Platt,Thomas Wagner +9 more
TL;DR: Wittrock et al. as mentioned in this paper presented the first global simultaneous observations of glyoxal (CHOCHO) and formaldehyde (HCHO) columns retrieved from measurements by the Scanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY) satellite instrument.
Journal ArticleDOI

Burrows,Annette Ladstaetter-Weissenmayer,Hani Moubasher +23 more
TL;DR: In this article, a comprehensive overview of the actual knowledge on the atmospheric pollution sources, transport, transformation and levels in the East Mediterranean is provided, focusing both on the background atmosphere and on the similarities and differences between the urban areas that exhibited important urbanization the past years: the two megacities Istanbul, Cairo and the Athens extended area.
Journal ArticleDOI
MAX-DOAS measurements of atmospheric trace gases in Ny- ˚ Alesund - Radiative transfer studies and their application
Folkard Wittrock,Hilke Oetjen,Andreas Richter,S. Fietkau,T. Medeke,A. Rozanov,John P. Burrows +6 more
TL;DR: In this paper, a new approach to derive tropospheric concentrations of some atmospheric trace gases from ground-based UV/vis measurements is described, which uses the sunlight scattered in the zenith sky as the light source and the method of Differential Optical Absorption Spectroscopy (DOAS) to derive column amounts of absorbers like ozone and nitrogen dioxide.
