Package ucar.nc2.dataset.conv

Class WRFConvention

java.lang.Object

ucar.nc2.dataset.CoordSysBuilder

ucar.nc2.dataset.conv.WRFConvention

All Implemented Interfaces:

CoordSysBuilderIF

public class WRFConvention
extends CoordSysBuilder

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

augmentDataset

public void augmentDataset(NetcdfDataset ds,
                           CancelTask cancelTask)

Description copied from interface: CoordSysBuilderIF

Make changes to the dataset that are needed before processing scale/offset in NetcdfDataset.

Specified by:

augmentDataset in interface CoordSysBuilderIF

Overrides:

augmentDataset in class CoordSysBuilder

Parameters:

ds - modify this dataset

cancelTask - give user a chance to bail out

makeCoordinateTransforms

protected void makeCoordinateTransforms(NetcdfDataset ds)

Description copied from class: CoordSysBuilder

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

Overrides:

makeCoordinateTransforms in class CoordSysBuilder

Parameters:

ds - why

getAxisType

protected AxisType getAxisType(NetcdfDataset ds,
                               VariableEnhanced ve)

Description copied from class: CoordSysBuilder

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 CoordSysBuilder

Parameters:

ds - for this dataset

ve - a variable alreaddy identified as a Coodinate Axis

Returns:

AxisType or null if unknown.

getZisPositive

public 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"

assignCoordinateTransforms

protected void assignCoordinateTransforms(NetcdfDataset ncDataset)

Assign CoordinateTransform objects to Coordinate Systems.

Overrides:

assignCoordinateTransforms in class CoordSysBuilder

Parameters:

ncDataset - why
