TL;DR: In this article, the authors present the new version (v14) of the BIRA-IASB algorithm for the retrieval of formaldehyde (H2CO) columns from spaceborne UV-visible sensors.
Journal ArticleDOI

Isabelle De Smedt,Nicolas Theys,Huan Yu,Thomas Danckaert,Christophe Lerot,Stephen Compernolle,Michel Van Roozendael,Andreas Richter,Andreas Hilboll,Enno Peters,Mattia Pedergnana,Diego Loyola,Steffen Beirle,Thomas Wagner,Henk Eskes,Jos van Geffen,K. F. Boersma,K. F. Boersma,Pepijn Veefkind +18 more
TL;DR: The formaldehyde (HCHO) tropospheric vertical column retrieval algorithm implemented in the S5P operational processor is introduced and comprehensively describes its various retrieval steps.
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
Global monitoring of volcanic SO2 degassing with unprecedented resolution from TROPOMI onboard Sentinel-5 Precursor.
Nicolas Theys,Pascal Hedelt,I. De Smedt,Christophe Lerot,Huan Yu,Jonas Vlietinck,Mattia Pedergnana,Santiago Arellano,Bo Galle,D Fernandez,C J M Carlito,Charlotte Barrington,Benoit Taisne,Hugo Delgado-Granados,Diego Loyola,M. Van Roozendael +15 more
TL;DR: It is found that TROPOMI surpasses any space nadir sensor in its ability to detect weak degassing signals and captures day-to-day changes in SO2 emissions, and is a factor of 4 better than the heritage Aura/Ozone Monitoring Instrument (OMI).
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.
