This icon derives (and returns) a vertical profile data unit of upper air fields for a particular point location (or small area). For each upper air field, values are interpolated at the point location (or integrated over the small area).

The vertical profile data can be plotted (using a default visualisation and with the plot area based on the range of data values) or saved as a NetCDF data file.A related icon, Vertical Profile View, is used to provide vertical profile plotting specifications. You can use it to visualise a vertical profile without explicitly deriving the vertical profile data - see Views

If access to the output computed values is not required, or for more control of the plotting, use the Vertical Profile View icon.

The macro language equivalent is mvert_prof().

The Vertical Profile Data Editor

Data

Specifies the data (GRIB icon) from which to derive the vertical profile data. 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. Note that the input fields should be on the same grid. If more than one time and/or forecast step is contained in the GRIB icon, Vertical Profile it returns a set of vertical profiles.

...

Specifies the output extraction mode. Valid values are Normal/ or Rttov.  The Rttov option is only valid internally at ECMWF and it is used in the context of the RTTOV model application.

Water Type

Valid values are Fresh Water or Ocean Water. Available when Output Mode is RTTOV Rttov.

Cloud Top Pressure

Pressure of the cloud top in hPa. Available when Output Mode is RTTOV Rttov.

Cloud Fraction

Available when Output Mode is RTTOV Rttov.
