Subject: | SGP/BRS/C1 - SWFANAL Data description error |
DataStreams: | sgp15swfanalbrs1longC1.c1 |
Description: | The long name attribute for the cloud effect fields incorrectly defines the cloud effect to be the difference between the clearskyfit and measured values: "Difference: ***fluxdn_clearskyfit - ***fluxdn_measured (***fcg)" ; The cloud effects are correctly calculated by subtracting the irradiance calculated in the clear sky fit from the measured irradiance. "Difference: ***fluxdn_measured - ***fluxdn_clearskyfit (***fcg)" ; NOTE: this is just a documentation error. The data are correctly calculated. |

DataStreams: | sgpirt10mC1.b1 |
Description: | The ground surface temperature exceeded the maximum measurement of 50C on some days. The maximum was increased to 60C for IRT10m on 10/1/2012 at 15:25 and for IRT25m on 10/9/2012 at 21:45. |

Subject: | SGP/IRT/C1 - 10m IRT ground surface temperature |
DataStreams: | sgpirt10mC1.b1 |
Description: | The 10m IRT was measuring lower ground surface temperature than the 25m IRT. The lens was cleaned on 12/19/2012 and replaced on 2/8/2013 but the difference in temperature appears to be due to the seasonal difference in surface cover - tall grass vesus bare soil. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgpirt10mC1.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. |
