Standard names by themselves are not always sufficient to describe a quantity. For example, a variable may contain data to which spatial or temporal operations have been applied. Or the data may represent an uncertainty in the measurement of a quantity. These quantity attributes are expressed as modifiers of the standard name. Modifications due to common statistical operations are expressed via the **`cell_methods`** attribute (see <> and <>). Other types of quantity modifiers are expressed using the optional modifier part of the **`standard_name`** attribute. The permissible values of these modifiers are given in <>.
