TL;DR: In this paper, the authors describe the development of a new, community best-practice NO2 retrieval algorithm based on a synthesis of existing approaches, and implement an enhanced spectral fitting method for NO2, a 1°''×''1° TM5-MP data assimilation scheme to estimate the stratospheric background and improve air mass factor calculations.

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.

TL;DR: The results of the Cabauw Intercomparison Campaign of Nitrogen Dioxide measuring Instruments (CINDI) as mentioned in this paper showed that the mean of the fitted slopes of all the visible MAX-DOAS instruments were within 10% of unity at almost all non-zenith elevations.

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: In this paper, shipborne multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements were performed during the TransBrom campaign over the western Pacific Ocean (≈ 40° N to 20° S).
