Topband: E layer ionograms

[Charles Hutton]

Thanks to Carl (offlist) and Tom for the responses.

Carl: I am actually looking for real data not calculated values. Part of the
reason why is exactly what you mentioned; Davies' formula is only valid for
the "normal" picture away from auroral effects, sporadic E, etc.

Tom: I've looked at UMass, Tromso, the English ionosonde sites, the
Australian IPC, NOAA/NTIS, U of Lethbridge, a couple of Russian sites, etc,
etc and not found any actual archives of a solar cycle or summaries of a
cycle. UMass has good stuff but I've never been able to find archives there.


Any more ideas? All ideas gratefully accepted.

Chuck

Chuck Asked:
Would any of the propagation people on the list know where I can find data
showing nighttime foE for a most or all of a solar cycle?


Try these guys at UMASS Lowell http://ulcar.uml.edu/ .They should have
archived what you are looking for.
