FREEZE LEVEL
Freeze Level data shows the color-coded contour lines for the altitude and location at which the first
isotherm is found (Figure 6-25). When no data is displayed for a given altitude, the data for that altitude has
not been received, or is out of date and has been removed from the display. New data appears at the next
update.
