Date Submitted: 10 May 1996
Submitted By: Jim Barnard _X_ Instrument Mentor
Platform/Measurement:
What level data: (raw,a0,a1,b1,c1 etc): raw,a0,a1
What location was the data collected at: E12
Period of time in question
Begin Date about 96/05/08
End Date 96/11/08
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 E12 has been out of alignment
from about 96/05/08 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 morning data.
Addendum: The end date of the alignment problem was determined to be 11/8/96.
During the period of this DQR, there were at least 5 attempts to re-align the
instrument. The last alignment was 11/7/96.
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). |
