Thank you all for the fast reply. Now I will slightly modify my initial question. My actual work is to define a Java ImageIO plugin able to read some NetCDF data to be used in GIS java applications. The actual version of the plugin requires data to be indexed as: Y,X if 2D T/Z,Y,X if 3D T,Z,Y,X if 4D In case, is the ncpdq tool capable of working on the same netCDF file having some variables with 4 Dimensions, while some other with 3, 2? Finally, how to handle variables with "time, lat, lon, outlev, vector" dimensions? Anyway, I will go to that link to know more info about such an useful tool.
