Journal ArticleDOI
Chemical ozone loss and ozone mini-hole event during the Arctic winter 2010/2011 as observed by SCIAMACHY and GOME-2

TL;DR: In this paper, the authors examined the composition and transformations occurring in the Arctic polar vortex using total column and vertical profile data products for O3, bromine oxide (BrO), nitrogen dioxide (NO2), chlorine dioxide (OClO), and polar stratospheric clouds (PSC) retrieved from measurements made by SCIAMACHY (Scanning Imaging Absorption SpectroMeter for Atmospheric CHartography).
Journal ArticleDOI

TL;DR: In this article, the results of the second Cabauw Intercomparison of Nitrogen Dioxide measuring Instruments (CINDI-2) were compared and validated against the colocated supporting observations.
Journal ArticleDOI
Ship-based MAX-DOAS measurements of tropospheric NO2 and SO2 in the South China and Sulu Sea
Stefan F. Schreier,Enno Peters,Andreas Richter,Johannes Lampel,Folkard Wittrock,John P. Burrows +5 more
TL;DR: In this paper, a ship-based multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements were performed within the SHIVA campaign on board RV Sonne in the South China and Sulu Sea.
Journal ArticleDOI
A study of the trace gas columns of O3, NO2 and HCHO over Africa in September 1997
Julian Meyer-Arnek,A. Ladstätter-Weißenmayer,Andreas Richter,Folkard Wittrock,John P. Burrows +4 more
TL;DR: The analysis reveals that the total amounts of HCHO generated over Africa during September 1997 as a result of biomass burning and biogenic emissions are similar, however the HCHO from biogenic sources has the highest specific columns and these are located close to their source.
Journal ArticleDOI
Slant column MAX-DOAS measurements of nitrogen dioxide, formaldehyde, glyoxal and oxygen dimer in the urban environment of Athens
Myrto Gratsea,Mihalis Vrekoussis,Mihalis Vrekoussis,Andreas Richter,Folkard Wittrock,Anja Schönhardt,John P. Burrows,Stelios Kazadzis,Nikos Mihalopoulos,Evangelos Gerasopoulos +9 more
TL;DR: In this article, spectral measurements from a ground-based multi-azimuth Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) system were successfully retrieved for the first time in Athens, by using spectral measurements.
