For questions or problems, please contact the ARM Experiment Center at
509-375-6898 or via email at dqr@arm.gov.
Platform/Measurement:
What level data: (raw,a0,a1,b1,c1 etc):
all levels for sgpsiros13
What location was the data collected at: SIROS CF
Period of time in question
Begin Date 19/OCT/94 Time 13:50 (GMT)
End Date 19/OCT/94 Time 21:15 (GMT)
Data should be labeled:
_x_ questionable _x_ All data fields affected
___ incorrect ___ Only some data fields affected
___ wrong calibration
___ others
Discussion of Problem:
A planned upgrade to the SIROS at the central facility extended
facility was performed by site personnel. Some data might be
missing, some might be out of range, and some might appear reasonable
but should not be trusted for the time interval and location specified.
Other observations/measurements impacted by this problem:
SMOS sensors when tower was down between 1420 and 1520 GMT; see DQR P941024.2.
MFR10 sensor when tower was down between 1420 and 1520 GMT, as noted in
a separate DQR
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
Flag data data with this comment.
