Platform/Measurement:
        What level data: (raw,a0,a1,b1,c1 etc): raw,a0,a1

    What location was the data collected at: E8
 
    Period of time in question
        Begin Date   about 96/04/18  
        End Date     ongoing problem  


 Data should be labeled:
 ___  questionable                      ___  All data fields affected
 _x_  incorrect                         _x_  Only some data fields affected
 ___  wrong calibration
 ___  others 
 
 Discussion of Problem: The MFRSR at site E8 has been out of alignment
from about 96/04/18 to the present time.  This is an ongoing problem.  The poor
alignment manifests itself in a sawtooth pattern in the direct beam and diffuse
components of the MFRSR data.  During the time this pattern exists, the data
are almost useless.  For this site, the poor alignment affects the afternoon data.
 
Other observations/measurements impacted by this problem:



Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.): align instument at
earliest possible time (Logistically, this is harder than it seems at
first glance).
Suggestions: 
Measurements:sgpsirosE8.a1:
  • direct_norm_narrowband
  • diffuse_hemisp_narrowband
  • diffuse_hemisp_broadband
  • direct_norm_broadband
