Impact of 3D cloud structures on the atmospheric trace gas products from UV–Vis sounders – Part 3: Bias estimate using synthetic and observational data
(Peer reviewed; Journal article, 2022)Three-dimensional (3D) cloud structures may impact atmospheric trace gas products from ultraviolet–visible (UV–Vis) sounders. We used synthetic and observational data to identify and quantify possible cloud-related bias ... -
Measurements of atmospheric aerosol vertical distributions above Svalbard, Norway, using unmanned aerial systems (UAS)
(Journal article; Peer reviewed, 2013) -
Observation of turbulent dispersion of artificially released SO2 puffs with UV cameras
(Journal article; Peer reviewed, 2018)In atmospheric tracer experiments, a substance is released into the turbulent atmospheric flow to study the dispersion parameters of the atmosphere. That can be done by observing the substance's concentration distribution ... -
On Aethalometer measurement uncertainties and an instrument correction factor for the Arctic
(Journal article; Peer reviewed, 2017) -
An optimised organic carbon∕elemental carbon (OC∕EC) fraction separation method for radiocarbon source apportionment applied to low-loaded Arctic aerosol filters
(Peer reviewed; Journal article, 2023)Radiocarbon (14C) analysis of carbonaceous aerosols is used for source apportionment, separating the carbon content into fossil vs. non-fossil origin, and is particularly useful when applied to subfractions of total carbon ... -
Real-time measurement of radionuclide concentrations and its impact on inverse modeling of 106Ru release in the fall of 2017
(Peer reviewed; Journal article, 2021)Low concentrations of 106Ru were detected across Europe at the turn of September and October 2017. The origin of 106Ru has still not been confirmed; however, current studies agree that the release occurred probably near ... -
Real-time UV index retrieval in Europe using Earth observation-based techniques: system description and quality assessment
(Peer reviewed; Journal article, 2021)This study introduces an Earth observation (EO)-based system which is capable of operationally estimating and continuously monitoring the ultraviolet index (UVI) in Europe. UVIOS (i.e., UV-Index Operating System) exploits ... -
A review and framework for the evaluation of pixel-level uncertainty estimates in satellite aerosol remote sensing
(Peer reviewed; Journal article, 2020)Recent years have seen the increasing inclusion of per-retrieval prognostic (predictive) uncertainty estimates within satellite aerosol optical depth (AOD) data sets, providing users with quantitative tools to assist in ... -
Satellite validation strategy assessments based on the AROMAT campaigns
(Peer reviewed; Journal article, 2020)The Airborne ROmanian Measurements of Aerosols and Trace gases (AROMAT) campaigns took place in Romania in September 2014 and August 2015. They focused on two sites: the Bucharest urban area and large power plants in the ... -
The added value of a visible channel to a geostationary thermal infrared instrument to monitor ozone for air quality
(Journal article; Peer reviewed, 2014) -
The Mineral Aerosol Profiling from Infrared Radiances (MAPIR) algorithm: version 4.1 description and evaluation
(Journal article; Peer reviewed, 2019)The Mineral Aerosol Profiling from Infrared Radiances (MAPIR) algorithm retrieves vertical dust concentration profiles from cloud-free Infrared Atmospheric Sounding Interferometer (IASI) thermal infrared (TIR) radiances ... -

Validation of SMILES HCl profiles over a wide range from the stratosphere to the lower thermosphere
(Peer reviewed; Journal article, 2020)Hydrogen chloride (HCl) is the most abundant (more than 95 %) among inorganic chlorine compounds Cly in the upper stratosphere. The HCl molecule is observed to obtain long-term quantitative estimations of the total budget ... -
Validation of the Sentinel-5 Precursor TROPOMI cloud data withCloudnet, Aura OMI O2–O2, MODIS, and Suomi-NPP VIIR
(Peer reviewed; Journal article, 2021)Accurate knowledge of cloud properties is essential to the measurement of atmospheric composition from space. In this work we assess the quality of the cloud data from three Copernicus Sentinel-5 Precursor (S5P) TROPOMI ... -
Validation of the TROPOspheric Monitoring Instrument (TROPOMI) surface UV radiation product
(Peer reviewed; Journal article, 2020)The TROPOspheric Monitoring Instrument (TROPOMI) onboard the Sentinel-5 Precursor (S5P) satellite was launched on 13 October 2017 to provide the atmospheric composition for atmosphere and climate research. The S5P is a ...
