A Record that is intended to contain meteorological conditions observed at an aerodrome.  This class is the result of MeteorologicalAerodromeObservation observations.<br /></p><p><br /></p><p>When no clouds of operational significance or no weather of operational significance is observed, the NothingOfOperationalSignificance nilReason should be used for the cloud or presentWeather association.  When no clouds were detected by the automatic observing system, the NotDetectedByAutoSystem nilReason should be used for the cloud association.<br /></p>
