Subject:
TWP/RL/C3 - Raw data time resolution change
DataStreams:twp10srlprofmr1turnC3.c0, twp10srlprofasr1ferrC3.c0
Description:
Normally, the Raman lidar operates using a 10 second averaging time for the raw data. 
However, during the period covered by the DQR, the averaging time was set to 30 seconds. This 
was done inorder to help diagnose a problem in the system.
Two datastreams (twp10sasr1ferrC3.c0, twp10smr1turnC3.c0) derived from the raw data 
inherently assume that the time resolution of the raw data is 10 seconds. This assumption 
should have no impact on the data quality. However, users should be aware that the actual time 
resolution is 30 seconds and not 10 seconds (during the period covered by this DQR).
Suggestions: 
Users should be aware that the actual time resolution is 30 seconds and not 10 

seconds (during the period covered by this DQR).
