| Description: | The KAZR 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. With the addition of Ka-SACRs adjacent to the KAZRs, this will give us an unprecedented method of doing calibration comparisons. The Ka-SACR will be able to use an external calibration target to include those components that are not calibrated by internal circuits. We will not be able to point the KAZR at a calibration target but by comparing radar returns to the Ka-SACR, we will be able to achieve a higher degree of calibration than we ever could with the KAZR operating standalone as its predecessor, the MMCR, did. 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, Kevin Widener, at kevin.widener@pnnl.gov as these issues occur so that they can be investigated and corrected if necessary. |
