Description: | At about 22:52 UTC on 2004/01/19, the NSA MPL appears to have suffered a temporary failure
of the laser Q-Switch. This results in a complete loss of lidar data immediately
thereafter. The problem was resolved (at least for the time being) by disconnecting and
reconnecting the Q-Switch cable on 2004/01/24 at about 00:16 UTC. Data after this time appears
good. |
