This dataset contains the number of infrasonic detections per day from four glaciers around Qaanaaq (Greenland) 
for the period 2004-2021. Four seperate files are given, one for each glaciers.

The files are named tnofG?.txt, and contain two columns time (t) and number of detections (nof) for G1,..,4. 
G1 is the Qaanaaq glacier 2 km north of the town of Qaanaaq. G2,..,4 or are 30km to the south of Qaanaaq on Steensby Land.  

tnofG?.txt are ASCII text files with the time ISO formatted in the first column as YYY-MM-DDThh:mm:ss. As the number 
of the detections per day are listed hh:mm:ss is chosen mid-day as 12:00:00. The second column contains the integer 
number of infrasonic detections on that day.
