| *The first value is the delay set on the pulse generator; the second one is the actual delay. | ||||||||||||
| #We set this delay using the time difference between the YAG trigger and outgoing UV laser trigger. | ||||||||||||
Range-corrected signal
Ceilometer data (UTC time)
Ozone retrieval (10-min resolution)
The channel-1 retrievals are higher than the sonde possibly due to aerosol or other systematic error.
