Subject: | SGP/MPL/C1 - Water intrusion |
DataStreams: | sgpmplpolfsC1.b1 |
Description: | Instrument temperatures were incorrect. On 02/01 and 02/03 they essentially flat lined at 0 C, while on 02/02 the temps were lower than normal (although given the external temp they may be accurate), with several data spikes throughout the day. Background signal values were excessively low throughout the entire period. Co- and cross-pol plotted values appear to have had a 3-5 km artificial elevation, resulting in plotted cloud bases appearing much higher than they actually were. System was not operating correctly due to water intrusion. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgpmplpolfsC1.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. |
