ENA/MAO/OLI/PGH/PVC/SGP/TWP/DLPROF/C1/C3/M1 - Reprocess: Suspect error estimates
DataStreams:enadlprofwind4newsC1.c1
Description:
The current dlprofwind4news VAP generates time- and height-resolved estimates of wind 
speed, wind direction, and corresponding uncertainties from Doppler lidar PPI scans. A recent 
comparison with a heavily instrumented tall tower (BAO) has shown that the error 
estimates are biased low and exhibit poor correlation with the observed lidar-tower differences. 
We note that the measurements themselves (i.e. wind speed and direction) are minimally 
affected by this issue.

ENA/GHG/C1 - Reprocessed and Corrected: Valve position fields incorrect type
DataStreams:enaaosghgC1.a1
Description:
DATA REPROCESSED and CORRECTED: 

The raw data variable mp_valve_position was being read as an integer instead of a float. 
The aos_ingest logic was corrected and the data were run through the corrected ingest to 
fix the issue.

The data were reprocessed in July 2016. Please retrieve the reprocessed data for use in 
your analysis.

You may find these data using the ARM Discovery tool at the following link:

ENA/CAPS-PMEX/C1 - Dirty optics
DataStreams:enaaoscapsC1.a1, enaaoscapsC1.00
Description:
During the time frame in question, there were several issues with the CAPS, including (i) 
very dirty optics - due to a tear in the purge lines that are used to keep the mirrors 
clean (ii) a significant reduction in S/N due to the dirty optics, (iii) which caused the 
raw loss to go way up and the noise level in grounding issue that required a new power 
supply. The latter issue necessitated removing the CAPS from the AOS to conduct several 
tests in the support building.

So in summary:
Negative extinction is unrealistic and was due to very dirty mirrors and control software 
issues.
Flatlining is due to the CAPS not being connected up because of troubleshooting.

Keep in mind that deployment of the CAPS at ENA was the first long term deployment of this 
instrument. Following this 'birthing' period, the unit has run exceptionally well.
