Subject:
SGP/RL/C1 - Decreased sensitivity
DataStreams:sgp10rlprofbe1turnC1.c0, sgp10rlprofdep1turnC1.c1, sgp10rlprofasr1ferrC1.c1, sgprlC1.00,

Description:
The sensitivity of the Raman Lidar degraded significantly beginning in late 2001.  Between 
May and September 2004, the electronics were upgraded and the telescope was refurbished 
resulting in sensitivity better than when the instrument system was first installed.

A detailed technical report describing the effects of the signal degradation and the steps 
taken to correct the problem is being written.  In the interim, contact Dave Turner 
(dave.turner@pnl.gov) for more information.
Suggestions: 
Data should be used with caution.  Contact Turner for more information.
