Subject:
HFE/NFOV/M1 - Over-ranging data
DataStreams:hfenfov2chM1.b1
Description:
The instrument was incorrectly installed with an incorrect range setting in the logger 
program.  The program for lamp calibrating the instrument was used, and not the operational 
program. The scale ranges are different, and this resulted in over-ranging conditions 
when the signal exceeded the upper end of the measurement scale.  Affected times are 
centered around solar noon, nominally +/- one-hour around solar noon.  This lasted until 
mid-Aug, when the highest signals were no longer exceeding the logger range.
Measurements:hfenfov2chM1.b1:
  • raw_counts_673nm
  • raw_counts_870nm
  • Calibrated Zenith Radiance, 673nm(radiance_673nm)
  • Calibrated Zenith Radiance, 870nm(radiance_870nm)
