Hi Ludovic, That's an interesting problem that we haven't seen before. Do any of the variables salinity, sndspeed, or density have an attribute named C_format, and if so, what is its value? Are these variables of type float or double? The problem you are seeing could be explained if they had attributes such as salinity:C_format="%.3gg" ; instead of salinity:C_format="%.3g" ; If that's not the problem, could you tell us what version of netCDF you are using, what operating system, and send us the output of "ncdump -c" on your file? Thanks! --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: GFG-507049 Department: Support netCDF Priority: Normal Status: Closed
