Subject:	TWP/MWR3C/C1 - Intermittent bad data
DataStreams:	twpmwr3cC1.b1
Description:	The radiometer has intermittent communication issues and part of the brightness temperature data is missing. The 30-feet cable connecting the positioner to the main junction box was replaced on 7/19.

Subject:	TWP/MWR3C/C1 - Incorrect data- bad calibration
DataStreams:	twpmwr3cC1.b1
Description:	The radiometer was started but the calibration was incorrect.

07/19/2013	0000	10/31/2013	2200	Incorrect

Subject:	TWP/MWR3C/C1 - Incorrect data
DataStreams:	twpmwr3cC1.b1
Description:	The hardware configuration of the W-band receiver was corrupted and the data were saturated. The K-band readings were constantly zero. The vendor suspects a failure of the noise diode. On 10/9/2013 a spare K-band receiver was installed and on 10/31 the settings of the W-band receiver were restored.

Subject:	TWP/MWR3C/C1 - Instrument not calibrated
DataStreams:	twpmwr3cC1.b1
Description:	The radiometer is not calibrating. On February 3 the radiometer was moved to avoid obstructions in the field of view. However the settings of the mean radiating temperature had to be adjusted.
Measurements:	twpmwr3cC1.b1: 30.0 GHz sky brightness temperature(tbsky30) 89.0 GHz sky brightness temperature(tbsky89) Column precip water vapor(pwv) 23.8 GHz sky brightness temperature(tbsky23) Liquid water path best-estimate value, hourly mean(lwp)
