Producing VVP Product Output

VVP product output consists of a data file containing the VVP parameters for each height. The displays are computed on-the-fly from the data file and are customizable. The available VVP displays in IRIS are:

• Line graphs against height

  Up to 5 parameters can be selected for plotting against height. Standard deviation bars are included on the plots.

• Time-height cross-sections

  Wind barbs, wind strings or axis of dilation/deformation lines are superimposed on a colored background of reflectivity, RhoHV, deformation, divergence or vertical velocity. Time scale and height are selectable.

You can select the display style, parameters, plot limits, and so on in the Output Options menu of the Quick Look window or Product Output Menu.

Thresholding in the displays is based on the goodness of fit of the velocity. In Output Options, you can set the threshold level between 0 (display all data) and 1 (threshold all data).
