Data types supported by netCDF

The data types supported by netCDF are character, byte, short, long, float, and double. These data types are maintained in the netCDF raster layer, feature layer, or table created from a netCDF file.

According to the CF conventionsLink to Unidata community website, variables representing time must always explicitly include the units attribute. The units attribute is a string value formatted as per the recommendations in the Udunits package. If a variable has one of the acceptable units for time, the data is represented as a date in ArcGIS.

The following table shows the netCDF data types and corresponding ESRI field types.
