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.

The macro language equivalent is mvert_prof().

Data

Specifies the data (GRIB icon) from which to derive the average 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, Average Vertical Profile returns a set of average cross sectionsvertical profiles.

Input Mode

Specifies whether to interpolate vertically the average cross-section values into a regular set of interpolated vertical levels. Choosing not to interpolate returns an average cross section data matrix with values at the original levels.Note - if you need to use the average cross section data in calculations further down the stream you should not interpolatederive the vertical profile for a Point or an Area. Nearest Gridpoint will take the nearest gridpoint to the point specified. Area 2 is an enhanced version of Area. It is more accurate and will work with a greater variety of projections. It should be used in preference to Area, which is included simply for backwards compatibility.

Point

Specifies the coordinates of the point for which the vertical profile is calculated. Enter coordinates (lat/long) of a point separated by a "/". Alternatively, use the coordinate assist button.

Area

Specifies the coordinates of the area over which the average profile is averages composing the vertical profile are calculated. Enter coordinates (lat/long) of an area separated by a "/" (top left lat and long, bottom right lat and long). Alternatively, use the coordinate assist button.

...

Output Mode

Specifies the direction along which the averaging of the variable is performed. Options are North South and East West. For North South, the averaging is weighted by cos(latitude).if the output file is to be used in the context of the RTTOV model application. In this case, extra parameters below need to be selected.

Water Type

Valid values are Fresh Water or Ocean Water.
