TL;DR: In this article, ground-based validation results of the atmospheric NO2 data produced operationally since April 2018 by the TROPOMI instrument on board of the ESA/EU Copernicus Sentinel-5 Precursor (S5p) satellite are compared to correlative measurements collected from, respectively, 19 Multi-Axis DOAS (MAX-DOAS), 26 NDACC Zenith-Scattered-Light DOAS, and 25 PGN/Pandora instruments distributed globally.

TL;DR: In this paper, the authors present intercomparison results for formaldehyde (HCHO) slant column measurements performed during the Cabauw Intercomparisons campaign of Nitrogen Dioxide measuring Instruments (CINDI) that took place in the Netherlands during two months, nine atmospheric research groups simultaneously operated MAX-DOAS (MultiAXis Differential Optical Absorption Spectroscopy) instruments of various designs to record UV-visible spectra of scattered sunlight at different elevation angles.

TL;DR: The CINDI campaign for Nitrogen Dioxide measuring instruments (CINDI) as discussed by the authors evaluated the accuracy of state-of-the-art ground-based measurement techniques for the detection of atmospheric nitrogen dioxide (both in-situ and remote sensing).

TL;DR: A complete overview of the calibration of SCIAMACHY is given to serve as a future reference for detailed studies into specific calibration issues and the effect of calibration problems on retrievals where possible.

TL;DR: In this paper, the authors analyzed ozone profiles from the recently reprocessed SHADOZ dataset that is based on adjustments for inconsistencies caused by varying ozonesonde instruments and operating techniques.
