Ron,
some years ago we found the BOM could do the same thing called a
pseudo temp
trace. Used it at the Bathurst state comps.
Give me a call if you need the BOM contact.
No need:
http://slash.dotat.org/cgi-bin/atmos
Unfortunately, whilst that does give sounding data, it only gives it for
places where there are actual soundings taken. What was being asked
about was the possibility of getting 'calculated' or 'modelled' sounding
data for any point in Australia as most gliding sites don't have a
sounding taken right over them.
This is where the NOAA site comes in - see my article at
http://www.hart.wattle.id.au/alice/gliding/SkewT-logPexplain.html for
information on how to obtain this and use it.
I have just updated that page to include a new table giving pressure
(hPa) vs height in 500 ft increments to make it easier to work out the
height from the pressure (which is what is plotted on the SkewT/LogP
diagram. This uses the NASA model for the standard atmosphere (see
references in the table itself).
