Specifies the data (GRIB icon) from which to derive 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 output. If more than one time and/or forecast step is contained in the GRIB icon, it returns a set of cross sections.
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.
