Class WRFConvention

java.lang.Object

ucar.nc2.internal.dataset.CoordSystemBuilder

ucar.nc2.internal.dataset.conv.WRFConvention

public class WRFConvention
extends CoordSystemBuilder

WRF netcdf output files.

Note: Apparently WRF netcdf files before version 2 didnt output the projection origin, so we cant properly georeference them.

This Convention currently only supports ARW output, identified as DYN_OPT=2 or GRIDTYPE=C

Method Detail

augmentDataset

public void augmentDataset(CancelTask cancelTask)

Overrides:

augmentDataset in class CoordSystemBuilder

makeCoordinateTransforms

protected void makeCoordinateTransforms()

Description copied from class: CoordSystemBuilder

Take all previously identified Coordinate Transforms and create a CoordinateTransform object by calling CoordTransBuilder.makeCoordinateTransform().

Overrides:

makeCoordinateTransforms in class CoordSystemBuilder

getAxisType

@Nullable
protected AxisType getAxisType(VariableDS.Builder v)

Description copied from class: CoordSystemBuilder

Identify what kind of AxisType the named variable is. Only called for variables already identified as Coordinate Axes. Default null - subclasses can override.

Overrides:

getAxisType in class CoordSystemBuilder

Parameters:

v - a variable already identified as a Coordinate Axis

Returns:

AxisType or null if unknown.

getZisPositive

public java.lang.String getZisPositive(CoordinateAxis v)

Does increasing values of Z go vertical up?

Parameters:

v - for thsi axis

Returns:

"up" if this is a Vertical (z) coordinate axis which goes up as coords get bigger, else return "down" TODO: doesnt seem to be used

assignCoordinateTransforms

protected void assignCoordinateTransforms()

Description copied from class: CoordSystemBuilder

Assign CoordinateTransform objects to Variables and Coordinate Systems.

Overrides:

assignCoordinateTransforms in class CoordSystemBuilder
