Access to the Dynasonde Database

At present the Dynasonde Database contains results of ionogram processing by the AutoDSND analysis software for three stations (Bear Lake Utah since 12 February 2003, EISCAT Tromsø since 10 June 2003, and Lycksele Sweden since 7 March 2004). The latest data available through the Database are for the previous complete UT day. Data for the most recent 48 hours is also accessible directly through the web interface on this site. The Database content is being supplemented continuously subject to normal operation of the stations. Further extension into the past is possible if historical data is made available to the NGDC.
