Subject: | SGP/MPL/C1 - Signal degrading |
DataStreams: | sgpmplC1.a1, sgpmplnor1campC1.c1
|
Description: | The MPL viewport window was blown off during a storm on 2002/09/25. The MPL received a
soaking of rain. Following this event, although site operations cleaned and dried the
optics, the lidar performance continued to degrade over the next few months. Although
initially suitable for cloud detection, by Dec 10th the lidar was providing useful results only
during the day (oddly enough). By Jan 16, the detector was dead.
It is not recommended to depend on night-time cloud base heights after Dec. 10 2002.
It is not recommended to use any of the data after 9/25 for aerosol retrievals. |

Description: | Sometime early 11/11 the detector on the
MPL-004 blew out. The Detector was replaced by Albert Mendoza.
The instrument was operational on Jan. 23, 1999.
Link this to P981119.2 that reported the blown detector and the
corrective action taken |
