Shear Markers displays two types of rings that represent the presence of significant shear. A
yellow ring indicates that the shear is in level 2 or above, while a red ring indicates a Low
Level Lock at level 1.
Upper level shear markers appear when the wind shear reaches
50 knots. Low Level Lock appears when the wind shear reaches
50 knots at level 1 and 30 knots at level 2.
Arrows displays NWS and Baron Services SCITs. A more detailed description of storm
arrows is in section 4.6, Storm Scan.
Lvl determines the sweep’s elevation level (1, 2, 3, or 4) for a product. Any product
described as using a certain number of scans uses this button to switch between levels.
The Product pull-down list lets you choose from any available
NEXRAD product. The menu will always show All Products even
after you choose a single one, but the radar image will show only
the product that you selected.
You may program the buttons above the product menu to display
your products in any configuration you wish. To change a button
product, right click on the button to open the Configure Panel
Button menu, shown to the right.
The text box at the top of the menu allows you to assign the text to
display on the button.
The second text box lets you enter the product code and modifiers.
The syntax for the code entry text box is as follows:
<product code> <lapse duration> <frame update> <options>
You can either type in the product code or select it from the menu below the text box.
<lapse duration> is the total lapse time in minutes, while <frame update> is the interval
between lapse frames in minutes. For example you could enter 13E 1440 5 to have the
product give a 24-hour lapse of reflectivity with a frame interval of 5 minutes (for a total of 288
frames).
There are two values you can enter in the options field:
Site=xxx overrides the site list box and specifies a single site for the button.
Lapse=n overrides the lapse checkbox and count.
Continuing the previous example, you could enter 13E 1440 5 site=C04 lapse=12 to
have the button give a 24 hour lapse of reflectivity with a frame interval of 5 minutes from site
C04 that repeats 12 times.
