Subject:	SGP/MWR3C/C1 - Incorrect or missing data
DataStreams:	sgpmwr3cC1.b1
Description:	The 89-GHz receiver started to reset itself continuously. The problem was initially identified with a wrong cable connection, but it was later found that one pin in the power connector of the receiver was broken. The pin was pulled out to temporarily start the radiometer. After the receiver was replaced it was discovered that there was an additional problem with water infiltration in the mini j-box. The mini-jbox was removed and sent for repair.

Subject:	SGP/MWR3C/C1 - Spikes in wind speed and direction
DataStreams:	sgpmwr3cC1.b1
Description:	The surface wind speed and wind direction wre occasionally spiking to large values during daylight hours. The spikes did not match well with co-located MET values. On 7/9 the wind sensor was replaced with a spare.

Subject:	SGP/MWR3C/C1 - Possible bias in 89 GHz brightness temperatures
DataStreams:	sgpmwr3cC1.b1
Description:	The 89 GHz brightness temperatures appear slightly warm when compared to model computations. The bias appear to be about 1.5 K. This could affect the liquid water retrievals that may display a slight positive bias.

Subject:	SGP/MWR3C/C1 - Intermittent data
DataStreams:	sgpmwr3cC1.b1
Description:	There are frequent data gaps between 3/9 and 3/18. The problem was due to a full hard drive.

Subject:	SGP/MWR3C/C1 - Precipitable water vapor and liquid water path are incorrect. Do not use.
DataStreams:	sgpmwr3cC1.b1
Description:	The 89 GHz channel readings are wrong because of a fault in the receiver thermal control. Precipitable water vapor and liquid water path are wrong.
Measurements:	sgpmwr3cC1.b1: 89.0 GHz sky brightness temperature(tbsky89) Liquid water path best-estimate value, hourly mean(lwp) Column precip water vapor(pwv)

Subject:	SGP Site Power Outage Due to Winter Storm
DataStreams:	sgpmwr3cC1.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.
