Subject:
SGP/BRS/C1 - Reprocess: Incorrect calibration coefficients
DataStreams:sgpbrsC1.b1, sgpbrs20sC1.a0
Description:
An incorrect serial number and calibration coefficients were used in processing.

Diffuse:  
  SN 33785 is correct. CF 110.28 is wrong; should be 107.45.

  Perform the following calculation to correct the data:
  DD= down_short_diffuse_hemisp:
  Instrument: SN 33785
  Old (incorrect) CF: 110.28  [W/m2\mv]
  New (correct) CF: 107.45 [W/m2\mv]
  DD (new) [W/m2] = DD (old) [W/m2] * 107.45 [W/m2\mv] / 110.28 [W/m2\mv]

Global:
  SN 30811 is correct. CF 128.79 is wrong; should be 120.77.

  Perform the following calculation to correct the data:
  DS= down_short_hemisp:
		
  Instrument: SN 30811
  Old (incorrect) CF:  128.79  [W/m2\mv]
  New (correct) CF: 120.77 [W/m2\mv]
  DS (new) [W/m2] = DS (old) [W/m2] * 120.77 [W/m2\mv] / 128.79 [W/m2\mv]


NIP:
  SN 34504 is correct. CF 118.17 is wrong; should be 123.19.

  Perform the following calculation to correct the data:
  NIP= short_direct_normal
		
  Instrument: SN 34504
  Old (incorrect) CF: 118.17 [W/m2\mv]
  New (correct) CF: 123.19 [W/m2\mv]
  NIP (new) [W/m2] = NIP (old) [W/m2] * 123.19 [W/m2\mv] / 118.17 [W/m2\mv]
Suggestions: 
Wait for reprocessed data.
