Purpose

This site is dedicated to the promotion of the ionosonde as a superior instrument for observing the ionosphere.

Content

This link is an animated GIF of ionograms from the Digisonde at Qaanaaq, Greenland.
It is the depiction of a sequence of 1 minute ionograms taken on 12 January 2002.  The series is almost 24 hours long. It shows interesting patch structure and the very dynamic nature of the high latitude ionosphere.  Note also the autoscaling is quite poor.
Qaanaaq 12Jan02
This animated GIF was created from the GIF images produced by the Artist4 ionogram scaler.  The linux program gifsicle was used to create the animation from the sequence of images.

Digisonde UDD Files

   Digisonde data users who use the UMass Lowell SAO Explorer program to analyze their data need something called a UDD file for each station.  The link below contains a list of the ones I have been able to collect.  Most of them are distributed with the SAO Explorer program.
UDD Files

ToDo --Latitudes, Longitudes, Dips and Gyrofrequencies are slightly inconsistent between these files.
I would like to obtain an official collection of these and update the UDD files accordingly.

Bill Wright and Adoph Paul wrote this report proposing a strategy for the positions for a global network of ionosondes.  This is a must read report for anyone considering setting up a new ionosonde station.
