Zeitlimit im Datensatz

Ich verwende Iris und Matplotlib, um zwei Datensätze visuell zu vergleichen (Karten, Liniendiagramme usw.). Beide Datensätze enthalten Zeit-, Breiten-, Längen- und Temperaturdaten. Die beiden Datensätze haben jedoch unterschiedliche Zeitreihen (eine von 1901-2007 und eine von 1950-2005). Wie kann ich die Datensätze so beschränken, dass ich Vergleiche in Bezug auf Zeit durchführen kann? Die Zeitdaten sind in diesem Format:Zeitlimit im Datensatz

Sie könnten eine Zeitbeschränkung definieren und die Integritätsbedingung zum Extrahieren aus dem Cube verwenden. Das Iris-Benutzerhandbuch enthält einen Abschnitt zu Einschränkungen. siehe http://scitools.org.uk/iris/docs/latest/userguide/loading_iris_cubes.html#constrained-loading. Von besonderem Interesse für uns wird der Unterabschnitt über die zeitliche Begrenzung sein, da wir hier eine zeitliche Beschränkung schaffen müssen.

In diesem Fall brauchen wir eine Zeitbeschränkung zu konstruieren, die verwendet werden können, von beiden Datensätze zu extrahieren alle Werte einschließlich in den Jahren 1950 - 2005. Sie können dies wie folgt tun:

iris.FUTURE.cell_datetime_objects = True 
t_constraint = iris.Constraint(time=lambda cell: 1950 <= cell.point.year <= 2005) 
shorter_series_1 = longer_series_cube.extract(t_constraint) 
shorter_series_2 = shorter_series_cube.extract(t_constraint)

Beachten Sie, dass strikt der zweite Extrakt (um shorter_series_2 zu machen) tut in diesem Fall nichts, aber ich habe es der Vollständigkeit halber aufgenommen. Der Aufruf iris.FUTURE bedeutet, dass wir Zellen (effektiv einen einzelnen Punkt und seine Grenzen von einer Koordinate) verwenden können, als ob sie Python-Datetime-Objekte wären. In diesem Fall können wir cell.point.year in der lambda innerhalb der Integritätsbedingung aufrufen.

Funktioniert die subset Methode, was Sie wollen?

z.

longer_series_cube.subset(shorter_series_cube.coord('time'))

bis Monate von der längeren Serie zu extrahieren, die die kürzere Serie entsprechen.

Subset ist eine gute Möglichkeit, diesen speziellen Fall zu lösen, bei dem die kürzere Koordinate vollständig von der längeren Koordinate enthalten ist - nette Lösung @RuthC! Eine allgemeinere Lösung wäre es, eine konsistente Einschränkung zu verwenden, um aus beiden Coords zu extrahieren - ich werde eine andere Antwort veröffentlichen, um diesen Ansatz zu demonstrieren. – DPeterK
