Meteorological data from Tarfala Ridge, northern Sweden

Tarfala Research Station staff

This dataset contains meteorological data acquired by Tarfala Research Station’s automated weather station located at Tarfala Ridge, northern Sweden. Tarfala Ridge is an important site for permafrost research, e.g. in the context of the EU-funded PACE (Permafrost and Climate in Europe) project, followed by the European Science Foundation network PACE-21 initiative, and then continued as part of Tarfala Research Station’s base program.

The measurements contained in this dataset start in September 2014 and are continuously updated, but the occasionally extreme conditions at the site pose a challenge to continuous data acquisition.

Meteorological variables reported here are: air temperature, relative humidity, short wave radiation, and wind speed.

Note that due to failure of sensors and/or batteries, not all variables are recorded at all times. Also, the frequency of measurement acquisition (e.g. values reported every 10 minutes, or every 30 minutes) can differ for different time periods.

Data description

The dataset consists of 11 csv files, named as CC_tarfala-tarfalaridge-meteorology_YYYY-MM_YYYY_MM.csv where CC = 01, 02, 03, to 11 is a counter, followed by the name of the dataset, and the time period YYYY-MM_YYYY-MM during which measurements were acquired (e.g. from September 2022 to September 2023).

The individual datafiles contain values for the following meteorological variables collected at Tarfala Ridge, geographical location: 67.91910 °N, 18.64160 °E, elevation 1550 m above sea level:

Variables

In all files

• date_time Date and time stamp (YYYY-MM-DD hh:mm) (in UTC+1).
• ta_avg Average air temperature (°C), 10 minute or 30 minute arithmetic mean of measurements conducted once per minute. Measured by a HygroClip 2S3 in a Solar Radiation Shield, at c. 2.4 m above ground.
• rh Relative humidity of air (%). Measured by a HygroClip 2S3 in a Solar Radiation Shield, at c. 2.4 m above ground. Transient measurement at output interval.
• sw_avg Incoming shortwave radiation (W/m²). Measured by a CS300, at c. 2.3 m above ground. Measured every ten seconds. Arithmetic mean of all readings within output interval.
• ws_avg Wind speed (m/s), measured by a Vector Instruments A100R Anemometer, at c. 2.4 m above ground. Measured every ten seconds. Arithmetic mean of all readings within output interval.
