Description

ELF-VLF observations have been carried out only during special
campaigns since 1989. In addition to broadband (500Hz-38kHz) VLF
campaigns SGO operates different kind of VLF observations including
receivers of AARDDVARK (Antarctic-Arctic Radiation belt (Dynamic) Deposition -
VLF Atmospheric Research Konsortia), WWLLN (World Wide Lightning
Location Network) and AWDA (Automatic Whistler Detector and Analyzer) networks.

This archive provides quicklook spectrogram plots of
VLF broadband data. These data were taken during observing
campaigns spanning the years 1993 through the present.
The archive contains plots made from data taken at four different
stations many of the plots are from 0 to 16 KHz and span 1 minute, 1hour, or 24 hour
duration.

The stations, locations and campaign date ranges are:

Porojärvi station (69.17° N 21.47° E)
