SGP/BRS/C1 - Reprocess: Incorrect Calibration Coefficients
|DataStreams:||sgpbrsC1.00, sgpbrsC1.b1, sgpbrs20sC1.a0|
Lightening strike on or near 6/2/2004 took the BRS NIP(31747E6) out of service, on or near 6/15 the NIP was replaced and the datalogger program was changed to reflect the new NIP(31343E6). On 8/5/2004 the DIR (Downwelling longwave) instrument was changed out and a new program was loaded to reflect a new DIR. The new program contained the original installed shortwave instrument calibration coefficients including NIP 31747E6. Thus from 8/5 to when the shortwave instruments were changed out on 12/3 the wrong s/n and calibration factor (i.e. 31747E6) was applied to the actual NIP(31343E6)installed at BRS C1.
Cal factors at time of installation for the NIPS: 31747E6 120.41 31343E6 119.22 NIP(cor)=(NIP (values during DQR period)/120.41)*119.22 This is a 1% difference , less than the uncertainty of the instruments.
