This icon is a plotting specification for Thermodynamic diagram plots from a suitable GRIB, BUFR and Input Visualiser icon data source. It can also take the output from a Thermo Data icon as an input. In this case, a consistency check is performed between the parameters that are common to both icons.

In addition to the parameters required for the Thermodynamic diagram computation, this icon specifies 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.

To access the computed output values use the icon Thermo Data.

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

From Macro/Python this icon can be called as thermoview().

Gallery examples using the Thermo View icon

The Thermo View Editor

Type

Specifies the type of the Thermodynamic diagram to be produced. Only Tephigram is currently implemented.

Bottom Pressure

Specifies the value at the bottom of the pressure axis of the thermodynamic diagram.

Top Pressure

Specifies the value at the top of the pressure axis of the thermodynamic diagram.

Minimum Temperature

Specifies the minimum value on the temperature axis of the thermodynamic diagram.

Maximum Temperature

Specifies the maximum value on the temperature axis of the thermodynamic diagram.

Thermo Grid

Configures the background attributes of the thermodynamic diagram, please see Thermo Grid.

Point Selection

Specifies how the geographical location, for which the diagram is to be plotted, will be selected. Options are: Coordinates, Area Average and Station.

Coordinates

Specifies the geographical location for which the diagram is to be plotted. Enter the coordinates (lat/long) of a point separated by a "/" (lat/long). Alternatively, use the coordinate assist button. Only available if Point Selection is Coordinates.

Area Average

Specifies a geographical area over which an area average value will be used, instead of a point value, to produce the diagram. Enter the 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. Only available if Point Selection is Area Average.

Station

Specifies the location for which the diagram is to be plotted. A Stations icon should be dropped here. Only available if Point Selection is Station.

Point Extraction

Specifies the way to calculate values at the point location for GRIB thermodynamic diagrams. Options are:

Interpolate - interpolate values from the four surrounding grid points (default)

Nearest Gridpoint - use the data from the nearest grid point

Dew Point Formulation

Specifies the equation to compute the Dew Point parameter. Options are: Saturation Over Water and Mixed Phase 0 to -23.

Temperature Param

Specifies the parameter number of the temperature, if the data is a non-ECMWF. ECMWF uses specific parameter numbers different from the WMO ones.

Specific Humidity Param

Specifies the parameter number of the specific humidity, if the data is a non-ECMWF. ECMWF uses specific parameter numbers different from the WMO ones.

Lnsp Param

Specifies the parameter number of the Lnsp, if the data is a non-ECMWF. ECMWF uses specific parameter numbers different from the WMO ones.

U Wind Param

Specifies the parameter number of the U wind component, if the data is a non-ECMWF. ECMWF uses specific parameter numbers different from the WMO ones.

V Wind Param

Specifies the parameter number of the V wind component, if the data is a non-ECMWF. ECMWF uses specific parameter numbers different from the WMO ones.

Map Overlay Control

Specifies details of the overlaying of data units in the same plot. Options are Always (default), By Date, By Level, Never.

Subpage X Position

Specifies the X offset of the plot from the left side of the plot frame (any subdivision of the display area). This is expressed as a percentage of the X-dimension of the plot frame.

Subpage Y Position

Specifies the Y offset of the plot from the bottom side of the plot frame (any subdivision of the display area). This is expressed as a percentage of the Y-dimension of the plot frame.

Subpage X Length

Specifies the X length of the plot. This is expressed as a percentage of the X-dimension of the plot frame. Hence the sum of this X length plus the X offset cannot exceed 100 (it is advised that it does not exceed 95 since you need some margin on the right for things like axis or map grid labels).

Subpage Y Length

As above but for the Y length of the plot.

Page Frame

Toggles the plotting of a border line around the plot frame On /Off .

Page Frame Parameters

Comprising Page Frame Colour, Page Frame Line Style and Page Frame Thickness, these parameters specify the characteristics of the plot frame border line. Only available when Page Frame is On .

Page Id Line

Toggles the plotting of plot identification line On /Off .

Page Id Line User Text

Specifies user text to be added to the plot identification line. Only available when Page Id Line is On .

Subpage Frame

Toggles the plotting of a border line around the plot itself On /Off . In most cases you will want this to be left On . When Off the sides of the plot not equipped with axis will not be plotted.

Subpage Frame Parameters

Comprising Subpage Frame Colour, Subpage Frame Line Style and Subpage Frame Thickness, these parameters specify the characteristics of the plot frame border line. Only available when Subpage Frame is On .

Subpage Background Colour

Specifies the colour of the background of the plot (i.e. not affected by visual definitions like contour shadings or lines).
