                         visad.DataReference minPresRef)
                  throws visad.VisADException,
                         java.rmi.RemoteException

Constructs from data references.

Parameters:

lclTempRef - The input LCL temperature reference.

lclPresRef - The input LCL pressure reference.

minPresRef - The input minimum-presure reference.

Throws:

visad.VisADException - if a VisAD failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.

Method Detail

compute

protected visad.Data compute(visad.Data[] datums)
                      throws visad.TypeException,
                             visad.VisADException,
                             java.rmi.RemoteException

Computes the output saturated, (AirPressure -> AirTemperature) lifted-parcel trajectory from the pressure and temperature at the Lifting Condensation Level (LCL) and the minimum pressure to which to lift the parcel.

Specified by:

compute in class ComputeCell

Parameters:

datums - The input data corresponding to the data references of construciton: datums[0] is the LCL temperature, datums[1] is the LCL pressure, and datums[2] is the minimum pressure.

Returns:

The corresponding lifted parcel path.

Throws:

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

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

visad.VisADException - if a VisAD failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.
