Bob, and others
Perhaps what you are referring to is setting up a system by which atmospheric
data can be collected simultaneous to a beacon, or series of beacons, used to
study propagation implications.
As you indicated, there is substantial information available. For a brief
description of what a "Radiosonde" is all about. Give this a quick read from
the U of Wisc. http://www.aos.wisc.edu/~hopkins/wx-inst/wxi-raob.htm
A substantial database exists that allows some collected data to be retrieved.
A quick perusal of the archives indicates and almost real time availability of
sophisticated Radiosonde data. Checking out the NOAA website on the subject:
http://raob.fsl.noaa.gov/ Although the format is somewhat awkward when
presented in the HTML format, I am fairly certain that the information can be
accessed in a meaningful manner for purposes of further study.
So if I understand you correctly Bob, you are indicating a series of beacons
with the radiosonde data superimposed on the data could provide us with an
improvement in our understanding of Topband propagation?
