Subject: | SGP/VCEIL/C1 - poor signal |
DataStreams: | sgpvceil25kC1.b1 |
Description: | When parameters were changed (set noise_h2_compensation to "ON" and units to "METERS") to correct a low amplitude problem, the backscatter plots began displaying horizontal stripes indicating detector "ringing". However, the cloud base heights are not affected. The problem was corrected when the instrument was replaced. |

Subject: | SGP/VCEIL/C1 - low amplitude |
DataStreams: | sgpvceil25kC1.b1 |
Description: | When the instrument was replaced with a spare, the backscatter plots began displaying a suspiciously low amount of amplitude (noise) but the cloud base heights were not affected. Discovered that when the vendor repaired this unit in August 2004, noise compensation was set to "OFF". Changed the parameters to "ON". Also noted that the measurement units was set to "FEET". This was changed to "METERS. The heights are not affected because the ingest recognizes the raw data units and automatically converts to meters. |
