Current state

original ICOADS data specifies both calm and variable winds with non-existing wind directions:

  • calm wind: wind direction = 361
  • variable wind: wind_direction = 362

As these values are not permitted for wind directions, these values will be changed during the mapping to the CDM:

  • 361 → 0
  • 362 → np.nan

Problem

There is no more differentiation between variable winds and non-existing wind directions (e.g. no data was transmitted; defective anemometer).
