...
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 latitude/longitude 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.
Area Average
Specifies a geographical area (lat1/lon1/lat2/lon2) 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.
Station
Specifies the location for which the diagram is to be plotted. In the Bufr Thermo dialogue, this must define a meteorological station that provides full upper air soundings. In the Grib Thermo dialogue, this may represent any arbitrary geographical point.
...
Specifies the way to calculate values at the point location for GRIB thermodynamic diagrams. Options are:
Interpolate - interpolate values from the surrounding grid points (default)
Nearest Gridpoint - using the data of 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.
