Auxiliary data for "Fluorescent aerosol particles in the Finnish sub-Arctic during the Pallas Cloud Experiment 2022 campaign"

This data set contains auxiliary data for the publication “Fluorescent aerosol particles in the Finnish sub-Arctic during the Pallas Cloud Experiment 2022 campaign” in Earth System Science Data.

Wind speed and wind direction were recorded at Sammaltunturi Station (67.9733°N 24.1157°E) at 564 m above sea level in the Pallas Atmosphere-Ecosystem Supersite in the sub-Arctic region of Finnish Lapland.

Snow depth was recorded at the Kenttärova research station (67.9873°N 24.242983°E, approximately 5.5 km east of Sammaltunturi).

Data were downloaded from the data download center of the Finnish Meteorological Institute (https://en.ilmatieteenlaitos.fi/download-observations, latest access: 12.08.2025). (Finnish Meteorological Institute open data, [meteorological observations])

The Sammaltunturi station is equipped with a Vaisala Milos 500 automatic weather station. The wind speed was measured with a heated cup anemometer and the wind direction with a heated wind vane.

The variables are:

“start time (UTC)”: The starting time of the one hour mean value of wind speed and wind direction in dd.mm.yyyy hh.mm in UTC.

“wind direction (deg)”: wind direction in degrees

“wind speed (m/s)”: wind speed in m/s

“date (UTC)”: The date of snow depth measurement (at 6:00 am UTC) in dd.mm.yyyy

“snow depth (cm)”: the snow depth (+/- 2 cm) in cm.
