Subject: | SGP/RL/C1 - Invalid liquid water channel data |
DataStreams: | sgprlC1.a0 |
Description: | On 20060906, the liquid water channel (LWC) was disabled due to the removal of its photomultiplier tube (PMT). Consequently, the signals recorded for the LWC contain either zero or pure noise after that date. Also, starting on 20070522, the LWC was populated with data from the T2 channel as a result of a slight reconfiguration of the data acquisition system. On 4 March 2008 The LW channel photomultiplier tube was reinstalled in the Raman lidar. Effective 0000 UTC on 5 March 2008 the LW channel began producing valid liquid water data once again. |

Subject: | SGP/RL/C1 - Degraded sensitivity in WFOV channels |
DataStreams: | sgprlC1.a0 |
Description: | The sensitivity of all the wide field-of-view (WFOV) channels was abnormally low due a malfunction of the filter wheel. The filter wheel for the WFOV channels did not rotate into position properly and thus partially obscured the return light. |
