https://www.pangaea.de/ information publisher tableDigital During a 2-week measurement campaign from 15-31 March 2021 (ISLAS2021), we collected a comprehensive dataset characterizing the atmospheric water vapour and precipitation stable isotope and aerosol composition at a coastal station in the European sub-Arctic. Located at the northeastern coast of the Nordic Seas, stable water isotope measurements with cavity ring-down spectrometers (CRDS) were collected at Andenes, Norway close to sea level and at the nearby ALOMAR mountain top observatory at 370 m a.s.l. Paired water vapour isotope and precipitation measurements at sub-event time resolution were collected at both station locations. These were supplemented with water vapour isotope measurements at the cities of Tromsø, Norway and Bergen, Norway. Surface precipitation samples were collected on a per-event basis along a transect towards the south to assess spatial representativeness. Measurements of ice nucleating particle concentrations were taken at sea level during precipitation events, supplemented by continuous size-resolved aerosol measurements. These detailed measurements were complemented by additional instrumentation to characterize the atmospheric conditions, including ground-based vertical-pointing rain radars, disdrometer, frequent radiosonde ascents and a ceilometer. All stable water isotope measurements have been calibrated onto the VSMOW-SLAP scale. During the campaign, weather conditions were alternating rapidly between warm mid-latitude air masses and marine cold-air outbreak conditions. The data from the ISLAS2021 measurement campaign therefore provide insight into a variety of mixed-phase precipitation processes, atmospheric long-range transport, and the dynamics of high-latitude weather system with the combined perspective of stable water isotopes and aerosol measurements. This dataset contains measurements of the stable isotope composition in water vapour from the site Tromsø in Tromsø, Norway, during the ISLAS2021 field campaign. The primary purpose for the collection of this dataset was to enable measurements of spatial distribution of water vapour isotope composition in Northern Norway. These water vapour measurements were obtained with a Picarro 2140-i cavity ring-down spectrometer installed in the city centre on top of the Physics building of the Arctic University in Tromsø. Isotopic data are accompanied by ambient air temperature, relative humidity, wind speed, and surface air pressure measured near the sample inlet. All data are time synchronised and averaged to 5 min time resolution. completed aerosols ALOMAR cavity ring-down spectroscopy INP ISLAS Norway precipitation profiles stable water isotopes water vapor theme 1995-01-01 creation PANGAEA
