AWR/KAZR/M1 - Snow Buildup
DataStreams:awrkazrgeM1.a1
Description:
Snow buildup from this system were affecting the sensitivity of the instrument.  Snow was 
cleared on 1/20/16 around 0200 UTC and shows up in the data as a sharp increase in Zh 
values.

AWR/KASACR/XSACR/M1 - General Quality Statement

Description:
The SACR continues to undergo evaluation by the radar instrument mentors, ProSensing, VAP 
developers, DQ Office, site scientists, users, etc.  As more in-depth analysis and 
calibration studies take place, we anticipate that new insights will be gained to increase the 
quality of the data and decrease the uncertainty of the measurements.  This is a 
continuous improvement process and issues will be addressed as they are discovered.

Calibration is very important.  Calibration of the SACRs depends on the careful 
installation of a corner reflector target.  This provides a external calibration reference not 
obtainable with a zenith-pointing radar such as the KAZR.  However, significant data analysis 
is required to assure that the radar is pointing at the target and there are no 
interfering losses in the transmission path.

As issues are discovered, attempts will be made to correct data that is currently in the
Archive.  However, retrospective correction of errors due calibration, signal processing,
component degradation and software bugs may not be possible for many of the data files.

This open-ended DQR is an advisory that some aspects of the data quality are not yet 
known.  It is also a request for users that find issues or questions with the data to contact 
the ARM Radar Engineering & Operations Group Manager, as these issues occur so that they 
can be investigated and corrected if necessary.
