I have frequently used the excellent Wetterzentrale website Archive Reanalysis pages to compare current Synoptics with historical ones but for some reason it will not open charts for the last couple of years. Old ones from dates prior to 2014 work fine but anything post 2015 just comes up with a Q box.

Does anyone have access to another site or are the newer charts hidden anywhere else on the Wetterzentrale pages?

Andy, for charts since 2014 I use this site: http://www.wetterzentrale.de/topkarten/tkfaxbraar.htm

They're only the fax style charts though, so they're surface pressure charts only without any upper air data, but I suppose that's better than nothing.  

This one gives the archive for GFS charts from 1999 up to the present day
