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.
Measurements:	sgpmwr3cC1.b1: 89.0 GHz sky brightness temperature(tbsky89) Liquid water path best-estimate value, hourly mean(lwp) Water vapor, precipitable, column-integrated on isobaric grid, from RUC model(pwv)

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