Validation of new satellite aerosol optical depth retrieval algorithm using Raman lidar observations at radiative transfer laboratory in Warsaw
(Journal article; Peer reviewed, 2018)During an exceptionally warm September of 2016, the unique, stable weather conditions over Poland allowed for an extensive testing of the new algorithm developed to improve the Meteosat Second Generation (MSG) Spinning ... -
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 FALL3D model for the 2008 Chaiten eruption using field and satellite data
(Peer reviewed; Journal article, 2013)The 2008 Chaitén Volcano eruption began on 2 May 2008 with an explosive phase that injected large amounts of tephra into the atmosphere. During the first week of the eruption, volcanic ash clouds were transported for ... -
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 ... -
Validation practices for satellite soil moisture retrievals: What are (the) errors?
(Peer reviewed; Journal article, 2020)This paper presents a community effort to develop good practice guidelines for the validation of global coarse-scale satellite soil moisture products. We provide theoretical background, a review of state-of-the-art ... -
Variability in Atmospheric Methane From Fossil Fuel and Microbial Sources Over the Last Three Decades
(Journal article; Peer reviewed, 2018)Atmospheric measurements show an increase in CH4 from the 1980s to 1998 followed by a period of near‐zero growth until 2007. However, from 2007, CH4 has increased again. Understanding the variability in CH4 is critical for ... -
Variations in tropospheric submicron particle size distributions across the European continent 2008-2009

Volcanic ash infrared signature: Porous non-spherical ash particle shapes compared to homogeneous spherical ash particles
(Journal article; Peer reviewed, 2014) -
Vulnerability and resilience of the carbon exchange of a subarctic peatland to an extreme winter event
(Journal article; Peer reviewed, 2018)Extreme winter events that damage vegetation are considered an important climatic cause of arctic browning—a reversal of the greening trend of the region—and possibly reduce the carbon uptake of northern ecosystems. ... -
WACCM simulations: Decadal winter-to-spring climate impact on middle atmosphere and troposphere from medium energy electron precipitation
(Peer reviewed; Journal article, 2020)Energetic particle precipitation is one of the main processes by which the sun influences atmospheric composition and structure. The polar middle atmosphere is chemically disturbed by the precipitation-induced production ... -
Warm Arctic–cold Siberia: comparing the recent and the early 20th century Arctic warmings
(Journal article; Peer reviewed, 2018)The Warm Arctic–cold Siberia surface temperature pattern during recent boreal winter is suggested to be triggered by the ongoing decrease of Arctic autumn sea ice concentration and has been observed together with an increase ... -
Webcrawling and machine learning as a new approach for the spatial distribution of atmospheric emissions
(Journal article; Peer reviewed, 2018)In this study we apply two methods for data collection that are relatively new in the field of atmospheric science. The two developed methods are designed to collect essential geo-localized information to be used as input ... -
