I am searching the grid with the values of the the surface air pressure to be used in GIS. Long term mean values or a record of multiple years are both fine. Preferably with a resolution smaller than 20km.
Thanks

Hi Stefano, you can find very good datasets at the European Center of Medium-Range Weather Forecast in Reading GB. There are forecast as well as reanalysis data ("historical") available. You could look for ERA 15, ERA 40, ERA 20, ERA Interim. They use different gaussian grids for leveled pressure data and also grids for the sea level pressure in an one or two minute resolution.
A dataset with a higher granularity for northern europe was generated Alexander Sokolov at the Nest Institute in Sweden (1km). The BED (Baltic Environmental Database) is unfortunally gone, but a mail to Alexander Sokolov could help you.
None grid stuff (raw data) with a very high station density can be found at ogimet.com, a spanish weather info provider. The colleagues there logging the synop weather telex stuff since 2000 and also metar/taf data from 2005 AFAIK. For me it is important to get weather data from the heli-pads and offshore oil-platforms hosted in that database.
May be GHCN is also an option but I think you now it.
PS.:I can give you a copy, if you cannot get the BED dataset from Alexander. I've aggregated some BED data sets including sea level pressure in 2007 during the IMKONOS project (BMBF Germany). I'ts open accessible.

Have you tried Climate Explorer? They are a portal - http://climexp.knmi.nl/start.cgi?id=someone@somewhere I think they're great
