The reporting resolution is 10 m or 100 ft depending on the selection.
If the cloud amount is zero, the corresponding layer height is ///.

-1
unless otherwise scaled by the
SCALE
parameter. Each sample is coded with a 20-bit HEX ASCII
character set; msb nibble and bit first, 2's complement. The length of
this line is equal to 5 times the length of the p 2. Note that the
profile is not corrected for the tilt angle.
Using the
SCALE
parameter a total dynamic range of 29 bits can be
achieved for this message.
