| 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. |
| Suggestions: | In most cases the reported low-level cloud bases will be accurate. However, use cloud base heights with some caution, particularly for any times for which MPL data are not available. |
