Subject: | SGP/QCRAD/E1 - Intermittently missing MFRSR data |
DataStreams: | sgpqcrad1longE1.c2, sgpqcrad1longE1.s2 |
Description: | Chunks of MFRSR data are missing during 20050514 - 20050712. After maintenance was performed on 20050712 the 415, 500 and 940 nm channels are available, and while they look OK, they should be used with caution. MFRSR data may be missing or zero; some tests on best estimate global shortwave cannot be applied. BEGSW could be incorrect if MFRSR data used in tests or fits. See instrument DQR D050521.1 |

Subject: | SGP/QCRAD/E1 - Missing surface met data |
DataStreams: | sgpqcrad1longE1.c2, sgpqcrad1longE1.s2 |
Description: | Surface meteorological data were missing during these time periods. Met data is used in a variety of quality control checks described below. Air temperature data is needed for tests on LW up and LW down pyrgeometer case and dome temperatures, and tests on the irradiances from upwelling LW/SW and downwelling LW. The Rayleigh limit diffuse radiation test is based on surface pressure. Most periods with missing data described in instrument DQRs: D991109.1, D080617.4, D080617.5 |

Subject: | SGP/QCRAD/E1 - Intermittently missing downwelling diffuse |
DataStreams: | sgpqcrad1longE1.c2, sgpqcrad1longE1.s2 |
Description: | Starting on or about 10/26/2005 the downwelling diffuse hemispheric irradiance (Eppley 8-48) instrument had intermittent missing values. Technicians found a loose wire on the instrument connector and repaired it on 4/4/2006. This means that Best Estimate Global can't be calculated from the sum of direct and diffuse. It also means that some quality checks can't be done. Problem documented in instrument DQR D060331.2. |

Subject: | SGP/QCRAD/E1 - Bad SWup data |
DataStreams: | sgpqcrad1longE1.c2, sgpqcrad1longE1.s2 |

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.
