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.  
  -(3/7/15 13:00: power drop)
  -(4/22/15 21:00 logger reset)

Diffuse:
DQR- reprocessing: 	
		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.
		-(3/7/15 13:00: power drop)
		-(4/22/15 21:00 Logger reset)

DQR- reprocessing:
                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.

DQR- reprocessing: 
		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.
