SGP/SIRS/E33 - Instrument noise problem
DataStreams:sgpsirs20sE33.a0, sgpsirsE33.b1
Description:
The UIR instrument (up_long_hemisp) had significant noise starting from the commission 
date.  On 8/14/2012 15:59 the UIR was replaced which corrected the noise problem.
Measurements:sgpsirs20sE33.a0:
  • inst_up_short_hemisp
  • inst_up_long_case_resist
  • inst_up_long_hemisp_tp
  • inst_up_long_dome_resist

Subject:
SGP/SIRS/E33 - Instrument noise problem
DataStreams:sgpsirsE33.b1, sgpsirs20sE33.a0
Description:
During troubleshooting of the UIR (up_long_hemisp) the UIR and DIR (down_long_hemsip) 
pyrgeometers were swapped to help isolate an instrument noise issue.  After this swap it was 
determined that the noise was associated with this specific instrument.

For the time range specified 8/14 to 8/17 the DIR data are not recoverable since the 
instrument was faulty (it was the old bad UIR). The instrument was replaced with spare on 8/17.

SGP/SIRS/E33 - Reprocess: Incorrect UIR calibration
DataStreams:sgpsirs20sE33.a0, sgpsirsE33.b1
Description:
During troubleshooting of the UIR (up_long_hemisp) the UIR and DIR (down_long_hemsip) 
pyrgeometers were swapped to help isolate an instrument noise issue.  

The replacement UIR instrument installed on 8/14 had incorrect calibration coefficients 
applied.  The serial number was correct.

wrong UIR k1 cal = 0.2376
correct UIR k1 cal = 0.2451

Data from 8/14 to 9/26 will be reprocess.

SGP/SIRS/E33 - Reprocess: Incorrect DIR calibration
DataStreams:sgpsirs20sE33.a0, sgpsirsE33.b1
Description:
During troubleshooting of the UIR (up_long_hemisp) the UIR and DIR (down_long_hemsip) 
pyrgeometers were swapped to help isolate an instrument noise issue.  That swap resulted in 
bad DIR data from 8/14-8/17 (documented in D121010.1)

A replacement DIR instrument installed on 8/17 had incorrect calibration coefficients 
applied.  The serial number was correct.

wrong DIR k1 cal = 0.2967
correct DIR k1 cal =  0.3086
