-Data variables must be one of the following data types: **`string`**, **`char`**, **`byte`**, **`unsigned byte`**, **`short`**, **`unsigned short`**, **`int`**, **`unsigned int`**, **`int64`**, **`unsigned int64`**, **`float`** or **`real`**, and **`double`** (which are all the [netCDF external data types](https://www.unidata.ucar.edu/software/netcdf/docs/data_type.html#external_types) supported by netCDF-4).

 The **`string`** type is only available in files using the netCDF version 4 (netCDF-4) format.
 The **`char`** and **`string`** types are not intended for numeric data.
 One byte numeric data should be stored using the **`byte`** or **`unsigned byte`** data types.
