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.)
