Constructor Detail

RelativeHumidity

protected RelativeHumidity(String name)
                    throws VisADException

Constructs from a name.

Parameters:

name - The name for the instance.

Throws:

VisADException - Couldn't create necessary VisAD object.

Method Detail

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.

create

public static Data create(Data mixingRatio,
                          Data pressure,
                          Data temperature)
                   throws TypeException,
                          VisADException,
                          UnitException,
                          RemoteException

Creates a water-vapor mixing-ratio data object from data objects for pressure and temperature.

Parameters:

mixingRatio - The mixing ratio

pressure - The pressure data object.

temperature - The temperature data object. If the in-situ temperature is used, then the returned object is the saturation mixing ratio. If the dew-point temperature is used, then the returned object is the actual mixing-ratio.

Returns:

Water vapor mixing-ratio or saturation mixing-ratio depending on the type of temperature.

Throws:

TypeException - At least one argument has incorrect type.

UnitException - Unit conversion failure.

VisADException - Couldn't create necessary VisAD object.

RemoteException - Java RMI failure.
