Comment: Added description of new parameters in 4.5.7

...

Specifies the parameter number of the general height-based coordinates if Vertical Coordinates is set to User.

 

W Wind Scaling Factor Mode

 

Specifies the algorithm to compute the scaling factor for the vertical wind component. Valid values are Automatic and User. Setting this option to Automaticwill compute a scaling factor taking into consideration the geographical area, the top/bottom pressure levels and the size of the plot window. Setting this option to User will apply a scaling factor defined by parameter W Wind Scaling Factor.

 

W Wind Scaling Factor

 

Specifies the vertical wind scaling factor if W Wind Scaling Factor Mode is set to User.

 

Level Selection Type

 

Specifies the method to define the output pressure levels when converting model level data to pressure levels. Options are:

 

  • From Data (default)
    • compute the absolute bottom pressure level from the data
    • for each model level, compute the average pressure along the cross section line and then use this mean pressure as the vertical pressure co-ordinate for that level
    • compute extra levels at the bottom by adding an offset (10 hPa) until it reaches the bottom pressure level, computed previously. This will avoid blank areas in the plot near the orography line.
  • Count
    • calculate the output pressure levels by taking into account the bottom and top pressure levels (Bottom Level and Top Level) and the given number of levels (Level Count). The computed levels will be evenly spaced on either a linear or a logarithmic scale depending on the value of Vertical Scaling.
  • Level List
    • use the given list of pressure levels (Level List)

 

Level List

 

Specifies a list of output pressure levels separated by a “/”. Only available if Level Selection Type is set to Level List.

 

Level Count

 

Specifies the number of output pressure levels if Level Selection Type is set to Count.

 

Vertical Scaling

Specifies the type of vertical axis - Linear or Logarithmic.
