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

Diffuse:  
  SN 33785 is correct. CF 107.57 is wrong; should be 107.45
  -(8/14/15 19:24 Sensor swap: 33785 removed. 33238 installed)

  Perform the following calculation to correct the data:
  DD= down_short_diffuse_hemisp:
  Instrument: SN 33785
  Old (incorrect) CF: 107.57  [W/m2\mv]
  New (correct) CF: 107.45  [W/m2\mv]
  DD (new) [W/m2] = DD (old) [W/m2] * 107.45 [W/m2\mv] / 107.57  [W/m2\mv]

Global:
  SN 30811 is correct. CF 120.63 is wrong; should be 120.77
  -(8/14/15 19:24 Sensor swap: 30811 removed. 30812 installed)

  Perform the following calculation to correct the data:
  DS= down_short_hemisp:
  Instrument: SN 30811
  Old (incorrect) CF: 120.63  [W/m2\mv]
  New (correct) CF: 120.77  [W/m2\mv]
  DS (new) [W/m2] = DS (old) [W/m2] * 120.77 [W/m2\mv] / 120.63  [W/m2\mv]

NIP:
  SN 34504 is correct. CF 123.18 is wrong; should be 123.19
  -(8/14/15 19:24 Sensor swap: 34504 removed, 29851 installed)

  Perform the following calculation to correct the data:
  NIP= short_direct_normal
  Instrument: SN 34504
  Old (incorrect) CF: 123.18  [W/m2\mv]
  New (correct) CF: 123.19  [W/m2\mv]
  NIP (new) [W/m2] = NIP (old) [W/m2] * 123.19 [W/m2\mv] / 123.18  [W/m2\mv]
Suggestions: 
Wait for reprocessed data.
