Cross Section tool

IRIS Focus calculates vertical cross sections from the product data for on-demand radar and lidar products.

The cross section window shows a vertical slice of the atmosphere on the selected line. The dotted lines are beam center lines that show the altitudes where the radar signal has passed at a given distance. The weather phenomena are drawn with the same colors as in the main view. The area outside radar range is greyed out.

Figure 1. Cross Section tool, CAPPI example
  1. In top right corner of the map view, select Tools > Cross Section.
  2. Select an on-demand radar or lidar product.
  3. Select points on the map:
    • Straight line – click on two points on the map to create endpoints for a vertical cross section of the product.
    • Curved line – Press Ctrl + click on the map and drag the mouse cursor to draw a freeform curved line and then release the mouse button.

    The cross section is calculated on a line between those endpoints.

    You can move the curve and the endpoints afterwards.

    If you are using an on-demand CAPPI product, the selected CAPPI altitude is drawn with a red line.
  4. If you wish, change the product data type from the drop-down menu.
