Subject:	SGP/ARSCL/C1 - Ceilometer not used during processing
DataStreams:	sgparsclcbh1clothC1.c1, sgparsclbnd1clothC1.c1, sgparscl1clothC1.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.
