Subject:
SGP/RLPROF/C1 - Reduced signal due to partially closed laser shutter
DataStreams:sgp10rlprofbe1newsC1.s1
Description:
The laser shutter was partially closed during the period in question. This resulted in a 
reduction in the sensitivity of all detection channels.

Subject:
SGP/RLPROF/C1 - Invalid data due to hatch closure
DataStreams:sgp10rlprofbe1newsC1.s1
Description:
The outgoing beam was completely blocked by the hatch. As a result, the data contain no 
valid atmospheric signals.

SGP/RLPROF/C1 - Reprocessed and Corrected: Incorrect units
DataStreams:sgp10rlprofbe1newsC1.s1
Description:
DATA REPROCESSED and CORRECTED: 

The units for water vapor mixing-ratio related variables in the rlprofbe1news VAP were 
incorrectly reported as g/km instead of g/kg. The netcdf files were modified and the data 
were reprocessed to address incorrect units issue. 

ORIGINAL DQR CATEGORY: Transparent(Does not affect quality)
