It looks fine as a netCDF file, but ncdump shows it has lots of "missing" data, represented in the ncdump output as "NaNf", which is the symbol used for a floating point "Not a Number", often used to represent missing values. Having missing values doesn't indicate the data is wrong, it could be intentional, such as data for sea-surface temperatures over land areas. Also, gdal_translate does the best it can with whatever metadata is available in the original geoTiff file, but if some metadata is missing, such as information needed to provide the lat/lon coordinates of the data, the resulting netCDF file won't be viewable over a map in the IDV. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: XBA-668885 Department: Support netCDF Priority: High Status: Closed
