Satellite Observations of Tropospheric and Stratospheric Gases
John P. Burrows,Andreas Richter,Mark Weber,Kai-Uwe Eichmann,Klaus Bramstedt,A. Ladstaetter-Weissenmayer,Folkard Wittrock,Michael Eisinger,L. Hild +8 more
TL;DR: In this article, the scientific requirements for stratospheric and tropospheric remote sensing are discussed and recent developments are reviewed and the development of atmospheric trace constituent remote sounding is discussed.
BrO Measurements from GOME and from the Ground: An Intercomparison Study
Andreas Richter,M. Van Roozendael,Tanja Wagner,Jean-Christopher Lambert,D. W. Arlander,John P. Burrows,Caroline Fayt,Paul Johnston,Roderic L. Jones,K. Karlsen Toernkvist,Karin Kreher,Klaus Pfeilsticker,U. Platt,I. Pundt,A. M. South,Folkard Wittrock +15 more
TL;DR: In this paper, the Global Ozone Monitoring Experiment (GOME) is used for the global measurement of ozone columns, but other trace gases such as NO-2, SO2, HCHO, BrO and OCIO can be retrieved from the spectra as well.

TL;DR: The SHIVA South China Sea (SCS) campaign as discussed by the authors investigated the emissions of Halogenated Very Short-Lives Substances (VSLS) from the SCS, their atmospheric transport and transformation, their contribution to the budget of ozone destroying halogens in the stratosphere.
Journal ArticleDOI
Validation of Sentinel-5P TROPOMI tropospheric NO2 products by comparison with NO2 measurements from airborne imaging DOAS, ground-based stationary DOAS, and mobile car DOAS measurements during the S5P-VAL-DE-Ruhr campaign

Santana Diaz,Nader Abuhassan,Dirk Schüttemeyer,John P. Burrows +29 more
TL;DR: In this article , a comparison of the AirMAP campaign data set to the scientific data products shows that the choice of surface reflectivity database has a minor impact on the tropospheric NO2 VCD retrieval in the campaign region and season.
Monitoring shipping emissions in the German Bight using MAX-DOAS measurements
André Seyler,Folkard Wittrock,Lisa Kattner,Barbara Mathieu-Üffing,Enno Peters,Andreas Richter,Stefan Schmolke,John P. Burrows +7 more
TL;DR: In this article, a 3-year time series of ground-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements of NO2 and SO2 on the island Neuwerk has been analyzed for contributions from shipping emissions.
