Subject:
SGP/MFRSR/E11 - Noise in broadband data
DataStreams:sgpmfrsrlangplotE11.c1, sgpmfrsrE11.a0, sgpmfrsrE11.b1, sgpmfrsrlangleyE11.c1
Description:
There was a lot of noise and drop outs in the open channel.  The problem was a connection 
issue.  The cables were all reseated.
Suggestions: 
Measurements:sgpmfrsrlangplotE11.c1:
  • log(irradiance) for the Direct Broadband(michalsky_lnI_broadband)
  • rejected points for the final fit for the Direct Broadband, Barnard(barnard_rejected_broadband)
  • rejected points for the final fit for the Direct Broadband(michalsky_rejected_broadband)
  • log(irradiance) for the Direct Broadband(barnard_lnI_broadband)
