Description

The Sodankyla Ionosonde started regular, half-hourly vertical soundings of the ionosphere on 1st August 1957. The observatory's second sounder (IS-14) was taken into operation on 1st February 1977. This sounder was modified later on. A new era of ionospheric vertical soundings began on 16th November 2005 when the new "Alpha Wolf" ionosonde was taken into use, which was built from scratch as a research ionosonde by the observatory during the previous three years. The new instrument performed soundings every 10 min until early April 2007, when 1-min soundings for the IPY began.
