Thank you very much for your ideas. Apparently FIMEX (
https://wiki.met.no/fimex/start) is the tool for this task. FIMEX seems to 
be able to make projections from NetCDF files with multiple layers to 
NetCDF files with multiple layers for (some?) proj4 projections!

Julia,
I think it kind of depends on what type of file format you need to 
output.  A 3-d dataset like this could easily be warped into a geotiff 
using gdalwarp from gdal.org.

Hi, 
i have a quite specific question and just wonder if someone has a good 
idea/ experience with this 

I need to project geographical referenced (WGS84) climate data (Europe in 
30 seconds) which is available as netCDF (dimensions: lon = 5160; lat = 
4560; time = UNLIMETED; // (1200 currently))  
to an equal area rectangular coordinate system (with 1x1km^2 resolution).

[The new projection is supposed to be: Projection: 
Albers_Conic_Equal_Area; Datum: European_Datum_1950; Units: Meters; 
Spheroid: International1924; lon0: 10, lat0: 30; lat1: 43, lat2: 62] 

Now i wonder which might be the best tool to project this NetCDF file. I 
found GMT, which seems to only able to project one layer at once and hence 
creates 1200 new files and then I found fimex, which I do not know yet, 
but it seems to be quite hard to compile..... 

Does anyone has experiences which such projections or the idea which tool 
does exactly what I need? 
Thank you very much for your help!
