Subject:
SGP/RL/C1 - Degraded sensitivity in WFOV channels
DataStreams:sgprlprofmerge1turnC1.c0, sgprlC1.a0
Description:
The sensitivity of all the wide field-of-view (WFOV) channels was abnormally low due a 
malfunction of the filter wheel. The filter wheel for the WFOV channels did not rotate into 
position properly and thus partially obscured the return light.
Suggestions: 
Be aware that all derived data products may exhibit increased noisiness at low altitudes.
Measurements:sgprlprofmerge1turnC1.c0:
  • Glue coefficient (slope) for low water vapor channel(water_counts_low_glue_coef_slope)
  • Glue coefficient (slope) for low elastic channel(elastic_counts_low_glue_coef_slope)
