  • Constructor Details

    • SaturationVaporPressure

      protected SaturationVaporPressure(String name) throws VisADException
      Constructs from a name.
      Parameters:
      name - The name for this quantity.
      Throws:
      VisADException - Couldn't create necessary VisAD object.

  • Method Details

    • getRealType

      public static RealType getRealType() throws VisADException
      Obtains the RealType associated with this class.
      Returns:
      The RealType associated with this class.
      Throws:
      VisADException - Couldn't perform necessary VisAD operation.

    • getRealTupleType

      public static RealTupleType getRealTupleType() throws VisADException
      Obtains the RealTupleType associated with this class.
      Returns:
      The RealTupleType associated with this class.
      Throws:
      VisADException - Couldn't perform necessary VisAD operation.

    • getTemperatureDerivativeRealType

      public static RealType getTemperatureDerivativeRealType() throws VisADException
      Obtains the RealType of the derivative with respect to temperature.
      Returns:
      The RealType of the derivative w.r.t. temperature.
      Throws:
      VisADException - Couldn't perform necessary VisAD operation.

    • create

      public static Data create(Data temperature) throws TypeException, UnitException, UnimplementedException, VisADException, RemoteException
      Creates a SaturationVaporPressure data object from a temperature data object. The algorithm is based on Bolton's 1980 variation of Teten's 1930 formula for saturation vapor pressure (see "An Introduction to Boundary Layer Meteorology" by Roland B. Stull (1988) equation 7.5.2d).
      Parameters:
      temperature - The temperature data object.
      Returns:
      Saturation water vapor pressure data object computed from the temperature. The type of the object will be that of the arguments after standard promotion.
      Throws:
      TypeException - Argument has wrong type.
      UnitException - Inappropriate unit argument.
      UnimplementedException - Necessary operation not yet implemented.
      VisADException - Couldn't create necessary VisAD object.
      RemoteException - Java RMI failure.

    • temperatureDerivative

      public static Data temperatureDerivative(Data temperature) throws TypeException, UnitException, UnimplementedException, VisADException, RemoteException
      Returns the derivative of saturation vapor pressure with respect to temperature.
      Parameters:
      temperature - The temperatures at which to return the derivatives.
      Returns:
      The derivative w.r.t. temperature at the given temperatures.
      Throws:
      TypeException - if a necessary RealType can't be created.
      UnitException - if unit-convertion failure occurs.
      UnimplementedException - if a necessary method is unimplemented.
      VisADException - if a core VisAD failure occurs.
      RemoteException - if a Java RMI failure occurs.

      Returns:
      Temperature data object computed from saturation water vapor pressures data object. The type of the object will be that of the arguments after standard promotion.
      Throws:
      TypeException - Argument has wrong type.
      UnitException - Inappropriate unit argument.
      VisADException - Couldn't create necessary VisAD object.
      RemoteException - Java RMI failure.
