OS = Operating system, 100 to 999
2 = Always 2
Samples = backscatter resolution and number of samples
1 = MESSAGE 107, 10 m x 770 samples, range 7700 m
2 = MESSAGE 108, 20 m x 385 samples, range 7700 m
3 = MESSAGE 109, 5 m x 1500 samples, range 7500 m
4 = MESSAGE 110, 5 m x 770 samples, range 3850 m
5 = MESSAGE 111, no backscatter profile
0 = MESSAGE 112, extended range, 5 m x 2048 samples, range 8000 m (samples after 1600 are

STX = Start-of-Text Character
CR LF = Carriage Line Feed
LINE 2
S WA V h1 V h2 V h3 V flags CR LF
where
S (1 character) = detection status:
0 = No significant backscatter
1 = One cloud base detected
2 = Two cloud bases detected
3 = Three cloud bases detected
4 = Full obscuration determined but no cloud base detected
5 = Some obscuration detected but determined to be transparent
/ = Raw data input to algorithm missing or suspect
WA (1 character) = Warning or alarm status:
0 = No alarm or warning
W = Warning
A = Alarm
h1 (5 characters) = 1st Height
If detection status is 1, 2, or 3 h1 = Lowest cloud base reported
If detection status is 4 h1 = Vertical visibility as calculated
If detection status is 0 or 5 h1 = /////
h2 (5 characters) = 2nd Height
If detection status is 2 or 3 h2 = Second cloud base reported
If detection status is 4 h2 = Highest signal received
If detection status is 0, 1, or 5 h2 = /////
