If the selected option is Area Hovm or Line Hovm and if more than one parameter and/or level is contained in the GRIB icon, Hovmøller Data returns a set of Hovmøller diagrams. However, if the selected option is Height Vertical Hovm, the GRIB icon should contain a set of levels for each parameter. Also, if the input data is specified in model levels, you must include the parameter LNSP should you want the vertical axis of the plot in pressure levels rather than model levels when visualising the output.
Average Direction (Area Hovm)
...
By default, the definition of the vertical and horizontal axes of the Hovmøller diagrams follows pre-defined rules. However, if Swap Axes is set to Yes then the axes will be swapped around.
Resolution
Used to interpolate the data onto a regular grid, and applies to both the horizontal and vertical axes where appropriate. This parameter is essential for creating a Hovmøller diagram from satellite data.
Vertical Level Type (Vertical Hovm)
Specifies if a conversion from model level to pressure level needs to be performed. Options are As In Data and Pressure, If the conversion to pressure is selected and the input data is specified in model levels, the LNSP field should be added to the input data.
Netcdf Data (Expand Hovm)
Specifies the data (Netcdf icon) from which to expand the Hovmoeller diagram.
Netcdf Path (Expand Hovm)
Specifies the Netcdf file path and name. Type the full file path and name. Alternatively, parameter Netcdf Data can be used.
Data Path (Expand Hovm)
Specifies the Grib file path and name. Type the full file path and name. Alternatively, parameter Data can be used.
