Subject: | SGP/SIRS/E13 - Instrument problem |
DataStreams: | sgpsirsE13.b1 |
Description: | up_long_hemisp measurements are intermittant and remain so after extensive troubleshooting. This problem will likly remain open ended until site ops can replace the cable which serves the up_long_hemisp instrument (i.e. the Eppley PIR). |

Subject: | SGP/SIRS/E13 - Reprocessed: Incorrect UIR calibration |
DataStreams: | sgpsirsE13.b1 |
Description: | For the time range specified the UIR had incorrect calibration coefficients applied. The k1 coefficient applied was 0.25042 when it should have been 0.2558. This resulted in the instrument under reporting up_long_hemsip by approximately 2.1%. Reprocessing completed 20121119 |

Subject: | SGP/SIRS/E13 - Upwelling LW hemisp connection |
DataStreams: | sgpsirsE13.b1 |
Description: | On 10/25 an intermittent problem began on the up_long_hemispheric (UIR) instrument dome thermistor which resulted in incorrect or missing calculated flux. Maintenance tightened connections on 11/21 which appears to have resolved the problem. |

Subject: | SGP/SIRS/E13 - UIR Instrument problem |
DataStreams: | sgpsirsE13.b1 |
Description: | Due to a bad connection the up_long_hemisp datastream (upwelling Epply PIR instrument) has intermittent missing data during the time range specified. Missing data are not recoverable. However, the sgpqcrad1longE13.c1 datastream adequately identifies missing values and removes them. Recommendation to the user is to use this VAP datastream for valid values of up_long_hemisp irradiance from this station. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgpsirsE13.b1 |
Description: | On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use. |
