Subject: | TWP/CEIL/C3 - Degraded hardware |
DataStreams: | twpceilC3.b1 |
Description: | It appears that the sensitivity of the Darwin ceilometer was degrading over a few month period leading up to September 2005. Beginning on September 16, 2005, the instrument shifted to a particularly bad state. Looking at the backscatter data, I do not see nearly as great a day-night difference in the background as I expect and there is very little sensitivity to clouds. There was cross talk error noted with that instrument. The ceilometer was replaced on December 12. |
