DataStreams: | sgpbrs20sC1.a0, sgpbrs60sC1.a1, sgpbrsC1.00, sgpbrsC1.a2 |
Description: | Downwelling shortwave (DS) values frequently drop below -10 W/m^2 at night, and are consistently 20-40 W/m^2 less than the calculated downwelling shortwave during the day in clear-sky conditions. Corrective maintenance on 12/1/2004 corrected this offset. It is not clear which CM action corrected the problem since the DS instrument cable was grounded to a new location and the DS ventilator fan was found in poor condition and was replaced. Either of these issues could have led to the problem observed in this instrument. |

Subject: | SGP/BRS/C1 - Monthly Summary |
DataStreams: | sgpbrsC1.b1 |
Description: | Data quality this site-month is poor. This is due largely to the missing Upwelling Shortwave and Upwelling Longwave the entire month. This problem has been ongoing for several months now. DQPR # 124 asserted that the Global PSP was recording inaccurate readings. Thus, the Global PSP was changed out on the 17th by site ops. Prior to the 17th, the Global PSP was falling below nighttime empirical limits on most nights and there were severe 3 component failures during the day. The change out of the PSP mitigated the severity of the 3 component failures and eliminated the nighttime empirical limits failures. There were still substantial 3 component flags after the 17th. |

Subject: | SGP/BRS/C1 - Reprocess: Incorrect Calibration Coefficients |
DataStreams: | sgpbrs20sC1.a0, sgpbrsC1.00, sgpbrsC1.b1 |
Description: | 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. |

Subject: | SGP/BRS/C1 - Monthly Summary |
DataStreams: | sgpbrsC1.b1 |
Description: | Data quality this site-month is good. The offset in the Global PSP has been much improved, with an average nighttime offset of -4 W/m^2, since measures were taken on 17 DEC 2004 to fix it. The Global PSP does not go below nighttime empirical limits all month. Global does fall below daytime empirical limits for significant time periods on the 2, 4, 5, 12, 28, 30. There were still substantial 3 component flags 17 DEC 2004. The charcteristic three component failures are present through out the month, especially closer to the end of the month. The problem is about equally as bad in the morning as the evening. The flags are usually high level yellow at their worst for any given day. Finally, there are the typical three component flags on the 29th as well, but these occur under cloudy skies. The data return to normal the next day and a cause for the problem cannot be determined. |

Subject: | SGP/BRS/C1 - Reprocessed: Longwave Calibration error |
DataStreams: | sgpbrsC1.b1 |
Description: | Modified pyrgeometer calibration procedures were implemented beginning in June 2004. These modified procedures introduced a calibration bias in the longwave data. The previous procedures were re-implemented at all sites between December 2005 and February 2006 to restore proper calibrations. The data collected while the incorrect procedures were in place have been reprocessed to remove the calibration bias. The reprocessed 60 second averaged data are based on 3 instantaneous 20 second data records rather than on 60 1 second instantaneous data records. Still, these data are considered far superior to the originally processed data. The reprocessed data were archived in November 2006. |
