050 1568 Meteorological Information

The report is not possible, because, with a temperature of 2°C and a dew point of 2°C there must be uniform fog. The report would never be seen, because shallow fog is not reported when the visibility is more than 2 km. The report is possible, because shallow fog is defined as a thin layer of fog below eye level. The report is nonsense, because it is impossible to observe a visibility of 5 km if shallow fog is reported.
