Not sure how long this has been here, but on the excellent Mitiociel

http://www.meteociel.fr/modeles/archives/archives.php
there is a facility to recall data from the NCEP 'Reanalysis'
project, from 1950. Now I know that Wetterzentrale.de have had such
for some time, but that site only has data for 00Z and for three
fields (850T on one chart & 500 gp/PMSL on another).
The Mitiociel archive has output for both 00Z and 12Z and for the
following fields (covering the North Atlantic/Europe-Mediterranean
region)
.. 500 hPa gp, PMSL
.. 850T, sig 850 windflow
.. 200 hPa 'jet' flow (might not be the jet of course but a good
proxy)
.. 850T & 'significant' thickness (or Relative Topography) isopleths.
You can plot all the charts at once, or each one individually.
There are also options for some fields covering the entire Northern
Hemisphere; however, I can only get a response for the last few years
- it may be that the database is under development for this function.
Nice one, Martin. It's a new one to me.
