Subject: | TWP/RL/C3 - Instrument problem |
DataStreams: | twprllogC3.a0 |
Description: | The system was mostly down during the period in question due a failure in the laser system. However, there were some brief and intermittent periods when data were acquired as the system was being worked on. The quality of these data is very questionable, and should not be used for scientific analysis. |
