Carbon monoxide, methane and carbon dioxide columns retrieved from SCIAMACHY by WFM-DOAS: year 2003 initial data set
Published 2005-01-01“…The CO<sub>2</sub> measurements over the Northern Hemisphere show the lowest mixing ratios around July in qualitative agreement with model simulations indicating that the large scale pattern of CO<sub>2</sub> uptake by the growing vegetation can be detected with SCIAMACHY. …”

The influence of natural and anthropogenic secondary sources on the glyoxal global distribution
Published 2008-08-01“…<br><br> The secondary anthropogenic contribution from fossil fuel and industrial VOCs emissions oxidation to the CHOCHO columns is found to reach 20–70% in the industrialized areas of the Northern Hemisphere and 3–20% in the tropics. This secondary CHOCHO source is on average three times larger than that from oxidation of VOCs from biomass burning sources. …”

Total ozone trends from 1979 to 2016 derived from five merged observational datasets – the emergence into ozone recovery
Published 2018-02-01“…However, for some latitudes, in particular the Southern Hemisphere extratropics and Northern Hemisphere subtropics, several datasets show small positive trends of slightly below +1 % decade<sup>−1</sup> that are barely statistically significant at the 2<i>σ</i> uncertainty level. …”

Global total ozone recovery trends attributed to ozone-depleting substance (ODS) changes derived from five merged ozone datasets
Published 2022-05-01“…</p> <p>The positive ODS-related trends in the Northern Hemisphere (NH) after 1995 are only obtained with a sufficient number of terms in the MLR accounting properly for dynamical ozone changes (Brewer–Dobson circulation, Arctic Oscillation (AO), and Antarctic Oscillation (AAO)). …”
