Subject: | SGP/RL/C1 - Reprocessing Notice (RID 1026) |
DataStreams: | sgprlprofmerge1turnC1.c0 |
Description: | See below for details of reprocessing that was completed on 20140822. Original DQR category:3 (Yellow, Suspect ). ----------------------------------------------------------- Regions where photon counting rates exceed 20 MHz are 37.5 meters too high. Correct data by shifting down 37.5 meters. Additional information: The detection system in the RL uses Licel data recorders. These recorders provide simultaneous measurements of analog voltage and photon counts from the photo multiplier tubes. The analog signal has an inherent delay relative to the photon counting signal, which is corrected for in the rlprofmerge VAP. The delay parameter is determined through offline analysis by the instrument mentor, and then inputted into a configuration file that is used by the VAP. During the effected period, the delay parameter for the narrow-field-of-view elastic channel was incorrect. As a result, the analog signal leads the photon counting signal by 5 range bins (5X7.5m = 37.5m). Photon counting rates that are outputted by the rlprofmerge VAP use the analog signals in regions where the photon counting rates exceed 20 MHz. So the counting rate data in these regions are (incorrectly) shifted downward by 37.5 m (i.e. -37.5m). |

Subject: | SGP/DL/DLPROF/C1 - Instrumental artifact in vertical velocity variance profiles |
DataStreams: | sgpdlprofwstats4newsC1.c1 |
Description: | Long-term averages of vertical velocity variance profiles developed from vertical staring data show a height-dependent sinusoidal modulation superimposed on the atmospheric variance profile. This modulation causes a wiggle in the variance profile. The period of the wiggle is about 350 m, and the effect is most obvious during hot afternoon periods in the summer months. The exact cause of this problem is not known, but we suspect that it may be caused by temperature sensitivity in beam alignment. |
