Page: 87 / 116

h5 (4 characters) = Height of the 5th cloud layer in 10s of
metres
or 100s of feet, if no 5th layer
is reported h5 = ////.
CR LF = Carriage Return + Line Feed
NOTE:
Cloud amounts and heights cannot be reported until the SkyVUE 8 has been operating for 30
minutes.

n (4 characters) = Profile length
energy (3 characters) = Laser pulse energy, %.
lt (3 characters including leading +/-) = Laser temperature, degrees C
ti (2 characters) = Total tilt angle, degrees
bl (4 characters) = Background light, millivolts at internal ADC input (0 to 2500)
pulse (4 characters) = Pulse quantity x 1000 (0000 to 9999)
