        "Description": "\nSGO ELF-VLF observations have been carried out only during special\ncampaigns since 1989. In addition to broadband (500Hz-38kHz) VLF\ncampaigns SGO operates different kind of VLF observations including\nreceivers of AARDDVARK (Antarctic-Arctic Radiation belt (Dynamic) Deposition -\nVLF Atmospheric Research Konsortia), WWLLN (World Wide Lightning\nLocation Network) and AWDA (Automatic Whistler Detector and Analyzer) networks. \n\nThis archive provides quicklook spectrogram plots of\nVLF broadband data. These data were taken during observing\ncampaigns spanning the years 1993 through the present.  \nThe archive contains plots made from data taken at four different\nstations many of the plots are from 0 to 16 KHz and span 1 minute, 1hour, or 24 hour\nduration.\n\nThe stations, locations and campaign date ranges are:\n\nPorojärvi station (69.17° N 21.47° E)\nCampaigns:\n1993-01-14 to 1993-01-29\n1993-11-09 to 1993-11-16\n1995-11-15 to 1995-11-29\n1997-01-06 to 1997-01-12\n\n\nKalkkoaivi station (68.73° N 22.11° E)\nCampaigns:\n1994-10-02 to 1994-10-08\n\nSiiselkä station (67.82° N 26.08° E)\nCampaigns:\n2005-09-26 to 2005-10-13\n\nKannuselehto station (67.74° N 26.27° E)\nCampaigns:\n2006-11-20\t2006-11-29\t\n2007-10-08\t2007-10-19\t\n2008-02-25\t2008-03-04\t\n2011-03-28\t2011-04-18\t\n2011-12-08\t2012-01-04\t\n2012-05-07\t2012-06-06\t\n2012-12-10\t2012-12-23\t\n2013-01-02\t2013-02-08\t\n2013-03-11\t2013-04-19\t\n2013-12-05\t2014-01-13\t\n2014-02-26\t2014-03-26\t\n2014-11-13\t2015-01-09\t\n2015-10-29\t2016-01-27\t\n2016-10-07\t2017-04-25\t\n2017-09-01\t2017-10-18\t\n2017-11-09\t2018-04-26\t\n2018-08-29\t2019-04-25\t\n2019-09-04\t2020-04-24\t\n2020-09-14\t2021-04-01\n\n\n\nTo get access to the numerical data contact Dr. J.
