Hi Jose...
The "GridDataset" you refer to is actually the domain sampling set --
usually a "visad.Gridded2DSet". Use the JPythonMethods method
"getDomainSet()" to get the Set for the FieldImpl.
Be a little careful about the structure of your "temperatures" object
-- if the first dimension is for "time", then you will need to
reference this as "temperature[0]" for the methods to work correctly.
(I usually just do a "print len(temperature)" and if the value is 1,
then I know I must use "temperature[0]" to reference the FlatField.)
