I wonder if this experiment could cause the North Polar Stratosphere Collapse-

"The SuperDARN/CUTLASS radars operated in a high resolution with time resolution of 1 second and range resolution of 15 km over the Tromsø heating region. The transmissions will be cycled quickly through three frequencies.-
The Heating facility is situated in Ramfjordmoen, near Tromso in northern Norway, next to the EISCAT UHF and VHF incoherent scatter radars. The facility was built by the Max-Planck-Institut fuer Sonnensystemforschung in collaboration with the University of Tromso..."
