Anmerkungen, Fragen
- Datei ist vollständig CF-konform - keine Erweiterungen erforderlich!
- Soll das BAW-Attribut name_id (für den Code) zusätzlich benutzt werden?
- Können wir Tiefenmittelwerte, z. B. für den Salzgehalt, aus den Daten und Metadaten problemlos berechnen?
- Oder sollen die Tiefenmittelwerte zusätzlich abgelegt werden?
- Können wir Vektoren zwischen verschiedenen Koordinatensystemen transformieren, um z. B. aus der x- und der y-Komponente die Ostkomponente zu berechnen?
- Wie kann ein sicherer Zusammenhang zwischen den Daten für die Schwebstoffklassen und den Klassennamen hergestellt werden?
- Kann der "suspended_matter_class_long_name" in dem Attribut coordinates genutzt werden?
- Ist es besser, die Daten der Schwebstoffklassen in einzelnen Feldern zu speichern? Dies wäre in Einklang mit den COARDS Konventionen.
