Virkisjökull Glacier Observatory weather station data and daily images

BGS Research — Glacier monitoring

The BGS’s Virkisjökull Glacier Observatory operated three automated weather stations (AWS) around the glacier. These were positioned at different heights (156 m, 444 m and 885 m) to determine changes in weather parameters with altitude, thus producing, for example, temperature or humidity gradients.

Each of our weather stations captured three images a day using robust, colour, two megapixel security cameras. These are viewable as timelapse videos or can be requested on an individual basis or covering a specified time period by contacting Jez Everest.

Weather station data

Temperature (°C)
Stations: AWS1, AWS3, AWS4, ASG1

AWS1, 3 and 4 measure air temperature every five seconds and an hourly average is displayed.

ASG1 records water temperature in the first minute of each hour.

Relative humidity (%)
Stations: AWS1, AWS3, AWS4

Stations record every five seconds and an hourly average is displayed.

Wind speed (metres per second)
Stations: AWS1, AWS3, AWS4

AWS1 and 3 use a traditional anemometer measuring every five seconds to produce an hourly average.

AWS4 employs an ultrasonic sensor measuring every five seconds to produce an hourly average.

Wind speed maximum (metres per second)
Stations: AWS1, AWS3, AWS4

AWS1 and 3 use traditional anemometers measuring every five seconds to determine maximum speed in an hour.

AWS4 employs an ultrasonic sensor measuring every five seconds to determine maximum speed in an hour.

Wind direction (degrees)
Stations: AWS1, AWS3, AWS4

AWS1 and 3 use a traditional wind vane measuring every five seconds to produce an hourly average.

AWS4 employs an ultrasonic sensor measuring every five seconds to produce an hourly average.

Pressure (hectopascals)
Stations: AWS4

AWS4 records measurements every five seconds and an hourly average is displayed.

Rainfall (millimetres per hour)
Stations: AWS1, AWS4

AWS1 uses a tipping-bucket rain gauge, which records numbers of ‘bucket tips’ to derive an hourly total.

AWS4 employs a rainfall impact sensor and converts impacts to rainfall volume to give an hourly total.

Solar flux (watts per square metre)
Stations: AWS1

AWS1 uses a pyranometer and records every five seconds and an hourly average is produced.
