Operational total and tropospheric NO 2 column retrieval for GOME-2
Pieter Valks,Gaia Pinardi,Andreas Richter,Jean-Christopher Lambert,Nan Hao,Diego Loyola,M. Van Roozendael,Sunil Emmadi +7 more
TL;DR: In this article, an algorithm for the operational near real time retrieval of total and tropospheric NO2 columns from the Global Ozone Monitoring Experiment (GOME-2) is presented.
Journal ArticleDOI
Improved retrieval of global tropospheric formaldehyde columns from GOME-2/MetOp-A addressing noise reduction and instrumental degradation issues
I. De Smedt,M. Van Roozendael,Trissevgeni Stavrakou,Jean-François Müller,Christophe Lerot,Nicolas Theys,Pieter Valks,Nan Hao +7 more
TL;DR: In this article, the authors presented a new dataset of formaldehyde vertical columns retrieved from observations of GOME-2 on board the EUMETSAT MetOp-A platform between 2007 and 2011.
Journal ArticleDOI
The GOME-2 total column ozone product: Retrieval algorithm and ground-based validation
Diego Loyola,Maria-Elissavet Koukouli,Pieter Valks,Dimitris Balis,Nan Hao,M. Van Roozendael,Robert Spurr,Walter Zimmer,Stephan Kiemle,Christophe Lerot,Jean-Christopher Lambert +10 more
TL;DR: The Global Ozone Monitoring Instrument (GOME-2) was launched on EUMESAT's MetOp-A satellite in October 2006 as mentioned in this paper, and the retrieval algorithm GOME Data Processor (GDP) version 4.4 is the latest version of the GDP 4.0 algorithm.
Journal ArticleDOI
Volcanic SO2, BrO and plume height estimations using GOME‐2 satellite measurements during the eruption of Eyjafjallajökull in May 2010
Meike Rix,Pieter Valks,Nan Hao,Diego Loyola,Hans Schlager,Heidi Huntrieser,Johannes Flemming,U. Koehler,Ulrich Schumann,Antje Inness +9 more
TL;DR: In this article, the SO2 and BrO columns in the eruption plume and the determination of the SO 2 plume height using the GOME-2 satellite instrument are described.
Journal ArticleDOI
First satellite detection of volcanic bromine monoxide emission after the Kasatochi eruption
TL;DR: In this paper, the transport of the volcanic plume has been simulated using the FLEXPART dispersion model, and evidence is found that the injection altitude of the BrO plume was located between 8 and 12 km altitude, i.e., in the upper troposphere/lower stratosphere region.
