SIROS 10M Data Release

This DQR needs to accompany SIROS 10 meter tower data release
from the Central Facility.  The SIROS 10 meter tower data release
is for the time period between August 18 and April 26, 1994.

Subject: SIROS 10M Data Release (April 26 thru August 18, 1994)

Platform/Measurement: 10 meter tower upwelling PIR 

        what level data: .a1 and .a0

 period of time in question
        start: April 26, 1994 at 00:00:00 (GMT)

        end:   August 18,1994 at 18:15:55  (GMT)


 Data should be labeled:
    - Incorrect     
    
 Discussion of Problem:
     - The preamp on the upwelling PIR signal was bad.
       During investigation of the raw data files, it was
       found that the UPIR signal was reading too high
       (2050-2200).  
  
Other observations/measurements impacted by this problem:
     

Suggested Corrections of the Problem:  None
