Re: [error]fatal:(lon) is not a named dimension in variable (var).

The most important rule in data processing is **look at your data**. From
printVarSummary(var)

Variable: var
Dimensions and sizes: [time | 360] x [j | 149] x [i | 182]
Coordinates:
            time: [15.5..10934.5]
            j: [1..149]
            i: [1..182]

There is no 'lat' dimension name. In fact, there are no latitude/longitude
coordinates on the file at all.
There is an attribute that tells you where you can get the file that
contains the needed information.

associated_files : baseURL: http://cmip-pcmdi.llnl.gov/CMIP5/dataLocation
gridspecFile: gridspec_seaIce_fx_IPSL-CM5A-LR_decadal1980_r0i0p0.nc
areacello: areacello_fx_IPSL-CM5A-LR_decadal1980_r0i0p0.nc

This is your responsibility to get this file. Unfortunately, this site
appears to be obsolete.
