Notes on the dynasonde soundings on this disk (DVDLR001) -------------------------------------------------------- LR is Longyearbyen, on Svalbard. The soundings come from the ex Halley Bay (Antarctica) sounder which was donated to EISCAT in 2007/2008. This disk contains mainly the archiveable .B_G soundings and a few other types. For analysed data etc., see dynserv.eiscat.uit.no Notes specific to this disk: ============================ The directory HAL_TOS contains a few soundings made with the ex Halley sounder while it was in Tromso, on the way to Svalbard. The sounder was turned off between 16 October 2008 and 1 Sept 2009. A disk crash on the local networked (Windows XP) PC resulted in data gap in the recordings between 31 Dec 2010 and 18 February 2011 when a new PC had been installed. A replacement of the preamp on the west antenna at 13:30 UT on 19 February 2011, which had been there since installation in 2008, resulted in a major improvement of sounding quality.
