The problem appears to be that at least the variable Float32 lap_fric_u[time = 1776][st_ocean = 89][yu_ocean = 382][xu_ocean = 273]; is too large to fit into a netcdf-3 variable. Remember that the netcdf-c library attempts to translate an opendap (i.e. DAP2) request into an equivalent netcdf-3 representation so that it can be accessed thru the netcdf API. The lap_fric_u variable size is 1776*89*382*273*4bytes = 65935449216bytes which is too big for netcdf-3. Can you send me the a url to the catalog entry on the thredds server for this dataset? If by some chance they have DAP4 enabled, then you should be able to at least get ncdump -h to work. > > as usual letters come if something does not work. Sorry.
