SGP/SIRS/E12 - Reprocessed and Corrected: Incorrect calibrations
DataStreams:sgpsirsE12.00, sgpsirsE12.b1, sgpsirs20sE12.a0
Description:
DATA REPROCESSED and CORRECTED: 

During a site corrective maintenance, the SIRS.E12 data logger was power cycled. The data 
logger reverted to an old SIRS program with incorrect S/Ns and calibration coefficients 
for all Instruments at this a station. The raw data were modified and were run through the 
ingest to recalibrate the SW and LW data.

The data were Archived in August 2016. Please retrieve the reprocessed data for use in 
your Analysis.

ORIGINAL DQR CATEGORY: Red( Incorrect)

---------------------------------------------------
--- ORIGINAL DQR DESCRIPTION ---
---------------------------------------------------


During site corrective maintenance to resolve an Extended Facility data collection 
problem, the SIRS.E12 datalogger was power cycled (1725 GMT).  The datalogger reverted to an old 
SIRS program with incorrect S/Ns and calibration coefficients for all instruments at 
this station.

The SW data can be recalibrated as follows:
First divide value by incorrectly applied cal coeff (first number) then multiply by 
correct cal coeff (second number)
  down_short_diffuse_hemisp     107.27	118.68
  up_short_hemisp	        113.19	127.95
  short_direct_normal           120.17	120.52
  down_short_hemisp             118.46	102.11

The LW data were recalibrated and reprocessed as part of a larger LW calibration task.  
The reprocessed data were archived in October 2006.
