Subject: | SGP/ECOR/E31 - Latent heat and CO2 fluxes incorrect |
DataStreams: | sgp30ecorE31.b1 |
Description: | The analog channels of the CO2/H2O sensor were missing due to a poorly seated connection. This results in incorrect fluxes. |

Subject: | SGP/ECOR/E31 - IRGA Serial Sampling Rate One Tenth of Normal |
DataStreams: | sgp30ecorE31.b1 |
Description: | The IRGA serial data sampling rate had somehow changed from 10 Hz to 1 Hz, reducing the size of the raw IRGA files by a factor of ten. No data quality was affected. |

Subject: | SGP Site Power Outage Due to Winter Storm |
DataStreams: | sgp30ecorE31.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. |
