Abstract. This paper reports on consolidated ground-based validation results of the atmospheric NO2 data produced operationally since April 2018 by TROPOspheric Monitoring Instrument (TROPOMI) board ESA/EU Copernicus Sentinel-5 Precursor (S5P) satellite. Tropospheric, stratospheric, and total column from S5P are compared to correlative measurements collected from, respectively, 19 Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS), 26 Network for Detection Atmospheric...

Abstract. Nitrogen oxides (NOx≡NO+NO2) in the NOx-limited upper troposphere (UT) are long-lived and so have a large influence on oxidizing capacity of formation greenhouse gas ozone. Models misrepresent NOx UT, observations to address deficiencies models sparse. Here we obtain year near-global seasonal mean mixing ratios NO2 UT (450–180 hPa) at 1∘×1∘ by applying cloud-slicing partial columns from TROPOMI. This follows refinement algorithm with synthetic GEOS-Chem chemical transport model....

Abstract. In this study the consistency between MAX-DOAS measurements and radiative transfer simulations of atmospheric O4 absorption is investigated on 2 mainly cloud-free days during MAD-CAT campaign in Mainz, Germany, summer 2013. recent years several studies indicated that can only be brought into agreement if a so-called scaling factor (<1) applied to measured absorption. However, many studies, including those based direct sunlight measurements, came opposite conclusion, there no...
Abstract. High-resolution Fourier transform infrared (FTIR) solar observations are particularly relevant for climate studies, as they allow atmospheric gaseous composition and multiple processes to be monitored in detail. In this context, the present paper provides an overview of 20 years FTIR measurements taken framework NDACC (Network Detection Atmospheric Composition Change) from 1999 2018 at subtropical Izaña Observatory (IZO, Spain).

Sea ice plays a crucial role in atmospheric chemistry. In the polar regions, particularly during spring, large amounts of bromine migrate from reservoir state sea to gas phase (Br2, BrCl) and subsequently reactive (Br, BrO). This involves autocatalytic processes which deplete surface ozone oxidizes toxic mercury, facilitating its entry into trophic chain.During last years, collaboration with Argentinian Antarctic Directorate/Argentine Institute, INTA has been performing long-term...
