Subject:	SGP/MMCR/C1 - Power supply failure
DataStreams:	sgpmmcrmomC1.00, sgpmmcrmomC1.b1, sgpmmcrspectraC1.a0, sgparscl1clothC1.c1, sgparsclbnd1clothC1.c1
Description:	A power supply failed in the MMCR's receiver. During the period of this DQR, the radar would appear to work but the calibration is probably incoorect during good portions of this time. The power supply was replaced and normal operation resumed at 2115 on 02/11/2005.

Subject:	SGP/ARSCL/C1 - Ceilometer not used during processing
DataStreams:	sgparscl1clothC1.c1, sgparsclbnd1clothC1.c1, sgparsclcbh1clothC1.c1
Description:	The ceilometer was not used during processing due to a ceilometer data format change that ARSCL did not handle properly. As a result, cloud boundaries in the lowest several kilometers may be less accurate than usual, as they are based solely on the micropulse lidar and millimeter cloud radar.
