This icon is a plotting specification for cross-section plots. It specifies the coordinates of the transect line and the axis details as well as the plot positioning in the plot frame of the display window / paper sheet and the overlay of different data units in the same plot.

This icon allows to create a cross-section plot directly from a suitable (multi-level) data unit without resorting to the use of the Cross Section Data application icon. A few input parameters are common to both icons. It is used for visualisation purpose only since the output values (e.g. the netCDF file) are computed and used internally (not available to the user).

Further details on the role and usage of View icons in the visualisation process, please see Views.

The macro language equivalent is mxsectview().

The Cross Section

Bottom Level

Specifies the data (GRIB icon) from which to derive lower limit of the cross -section profile. The input GRIB icon must specify a multi-level (pressure or model levels) upper air meteorological variable, in a latitude-longitude or Gaussian grid. 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 outputsection, as a pressure level (hPa) or model level (η levels).

Top Level

Specifies the upper limit of the cross section, as a pressure level (hPa) or model level (η levels).

Interpolate Values

Specifies whether to interpolate vertically the cross-section values into a regular set of interpolated vertical levels. Choosing not to interpolate returns a cross section data matrix with values at the original levels.
