I'm thinking that being able to access #ionosonde data from a nearby station, either Austin or Boulder, would be an easy way to get useful info such as the critical frequency, maximum usable frequency, etc. #AmateurRadio #HamRadio #accessib
Does anyone know if there's any interpreted #ionosonde data from #ionograms available in an accessible format? All I'm finding so far are just the PNG images without descriptions, even from Section 508 covered agencies like #NOAA. #accessib

What “ionosonde” means
WikipediaAn ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton. The term ionosphere and hence, the etymology of its derivatives, was proposed by Robert Watson-Watt.
