or to a series of cloud cover (n) in percent or oktas.

Details
Input:
A SEF file or a data frame and metadata. The observations data frame
must have five or seven columns: variable code, year (YYYY), month (MM), day
(DD), (hour (HH), minute (MM)), observation.
Output:
A text file of flagged observations with six or eight columns: variable
code, year (YYYY), month (MM), day (DD), (hour (HH), minute (MM)),
observation, test. The test column has the description "gross_errors".
The flagged observations correspond to values that don't belong to the
integer interval (0, 100) if the unit is percent or that don't belong to the
integer interval (0, 9) if the unit is oktas.
