Abstract The Aerosol, Clouds and Trace Gases Research Infrastructure (ACTRIS) officially
became the 33rd European Research Infrastructure Consortium (ERIC) on 25 April 2023 …

Over the last five decades, Earth's atmosphere has been extensively monitored from space
using different spectral ranges. Early efforts were directed at improving weather forecasts …

Abstract TROPOMI (the TROPOspheric Monitoring Instrument), on board the Sentinel-5
Precursor (S5P) satellite, has been monitoring the Earth's atmosphere since October 2017 …

High-resolution Fourier transform infrared (FTIR) solar observations are particularly relevant
for climate studies, as they allow atmospheric gaseous composition and multiple climate …

Spaceborne formaldehyde (HCHO) measurements constitute an excellent proxy for the
sources of non-methane volatile organic compounds (NMVOCs). Past studies suggested …

Heatwaves are a substantial health threat in the UK, exacerbated by co-occurrence of ozone
pollution episodes. Here we report on the first use of retrieved vertical profiles of nitrogen …

We describe new publicly available, multi‐year formaldehyde (HCHO) data records from the
Ozone Map** and Profiler Suite (OMPS) nadir mapper (NM) instruments on the Suomi …

Multi-A**s Differential Optical Absorption Spectroscopy (MAX-DOAS) is a well-established
ground-based measurement technique for the detection of aerosols and trace gases …

Volatile organic compounds (VOCs) are key precursors of particulate matter and
tropospheric ozone. Although the terrestrial biosphere is by far the largest source of VOCs …

Isoprene is the dominant nonmethane organic compound emitted to the atmosphere, where
it drives ozone and aerosol production, modulates atmospheric oxidation, and interacts with …
