Subject:	NSA/HSRL/C1 - Degraded operation
DataStreams:	nsahsrlC1.a1
Description:	The HSRL was suffering from operational issues following an enclosure overheating incident. Data continued to be collected, albeit with reduced power output, detection sensitivity, and calibration issues. It has utility for cloud and aerosol detection but must be used with caution. Heights and locations are quantitative and reliable, intensities are not.

Subject:	NSA/HSRL/C1 - Degraded operation, laser instability, dirty window
DataStreams:	nsahsrlC1.a1
Description:	Following installation instrument was still not operating optimally. Laser instability and reduced sensitivity were impacting measurements. Cleaning of the external window improved signal levels and sensitivity on March 18 17:30. The height of detected clouds and aerosols is quantitative and accurate however the calibrated backscatter quantities are uncertain. Nevertheless, the sensitivity of the HSRL even in this degraded capacity is superior to VCeil and MPL for cloud and aerosol detection.

Subject:	NSA/HSRL/C1 - Laser instability
DataStreams:	nsahsrlC1.a1
Description:	The HSRL laser still exhibits instability causing calibration uncertainty, especially for the beta_a (extinction profile), beta_a_backscatter (backscatter profile), and depol (depolarization ratio). Cloud and aerosol layer heights are quantitative and accurate however the calibrated quantities above have increased uncertainty. Nevertheless, the sensitivity of the HSRL in this degraded mode is still superior to other lidar on site (MPL and VCeil). The laser failed on 07/19/2013 at 22:30.

Subject:	NSA/HSRL/C1 - Laser failure
DataStreams:	nsahsrlC1.a1
Description:	Starting at around 08:00 UTC on July 20, the HSRL laser output stopped. The laser was repaired by UW SSEC staff on Sept 10 but instrument work continued until Sept 15 22:00 UTC. All lidar profiles in this time period should be deemed "bad" and not used.
