LclTemperatureCell

public LclTemperatureCell(DataReference ratioRef,
                          DataReference initPresRef,
                          DataReference initTempRef)
                   throws VisADException,
                          RemoteException

Constructs from data references for the water-vapor mixing-ratio and the initial pressure and temperature.

Parameters:

ratioRef - The input water-vapor mixing-ratio reference.

initPresRef - The input initial pressure reference.

initTempRef - The input initial temperature reference.

Throws:

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.

Method Detail

compute

protected Data compute(Data[] datums)
                throws TypeException,
                       VisADException,
                       RemoteException

Computes the output condensation temperature (the temperature at the LCL) from the water-vapor mixing-ratio and the initial pressure and temperature.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data in the same order as during construction: datums[0] is the water-vapor mixing-ratio; datums[1] is the initial pressure; and datums[2] is the initial temperature.

Returns:

The corresponding condensation temperature.

Throws:

ClassCastException - if an input data reference has the wrong type of data object.

TypeException - if a VisAD data object has the wrong type.

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.
