SGP/RL/C1 - Alternatively processed data available
DataStreams:sgp10rlprofmr1turnC1.c1
Description:
Reprocessed ARM Raman Lidar water vapor data is available for 
               the IHOP IOP period 20020515 to 20020625 at 
               http://iop.archive.arm.gov/arm-iop/2002/sgp/ihop/turner-raman/
               The data were reprocessed by Dave Turner to apply an improved 
               near-field correction ("overlap correction") to the water
               vapor data collected by the Raman lidar during IHOP.  These
               files contain only the water vapor data; users who require the
               aerosol and cloud fields from this instrument will need to
               retrieve the regular ARM data sets.

SGP/RL/C1 - Metadata errors
DataStreams:sgp10rlprofmr1turnC1.c1
Description:
The latitude, longitude and altitude of the Raman Lidar were
incorrectly entered into the ARM database.  The correct location
of the SGP.C1 Raman Lidar is:
      Lat: 36.609N
      Lon: 97.487W
      Alt:    311m
Measurements:sgp10rlprofmr1turnC1.c1:

Subject:
SGP/RL/C1 - Decreased sensitivity
DataStreams:sgp10rlprofmr1turnC1.c1
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.
