Subject: | SGP/QCRAD/E1 - Tracker malfunction |
DataStreams: | sgpqcrad1longE1.c2, sgpqcrad1longE1.s2 |
Description: | The solar tracker was inoperative during these time periods indicating that the shortwave direct normal, the shortwave diffuse, and possibly the downwelling longwave irradiance are inaccurate. This also impacts the best estimate value because the sum of direct and diffuse cannot be used, and some tests can't be applied to the data. Some problems documented in instrument DQRs: D090520.1 & D090121.1 |

DataStreams: | sgpqcrad1longE27.c1, sgpqcrad1longE27.c2, sgpqcrad1longE27.s1, sgpqcrad1longE27.s2 |
Description: | Possible main power problem made may have caused the tracker to fail. Attempts to restart the old tracker, subsequent replacement and lack of spares contributed to incorrect data from the NIP (short_direct_normal datastream) and 8-48 (down_short_diffuse_hemisp datastream) until the time of site decommissioning. This facility was decommissioned and maintenance efforts ceased 10/1/2009. The instrument was removed from service 12/04/2009. Documented in instrument DQR D090609.1 |

DataStreams: | sgpqcrad1longC1.c1, sgpqcrad1longC1.c2, sgpqcrad1longC1.s1, sgpqcrad1longC1.s2 |
Description: | NIP cable had failed during this time period. Short_direct_normal data are not recoverable during this time period. However, it can be reconstructed using the following formula for each one minute data: short_direct_normal = (down_short_hemisp-down_short_diffuse_hemisp)/cos(zenith angle) Documented in instrument DQR D090623.1 |

DataStreams: | sgpqcrad1longC1.c1, sgpqcrad1longC1.c2, sgpqcrad1longC1.s1, sgpqcrad1longC1.s2 |
Description: | The upwelling shortwave hemispheric (up_short_hemisp) data were missing or incorrect due to a bad cable. Cable was replaced on 6/30 and the problem was resolved. Documented in instrument DQR D100701.1 |
