Subject:	GAN/MWR3C/M1 - Intermittent data
DataStreams:	ganmwr3cM1.b1
Description:	The data stops every day at 12 pm because of an error in the schedules tasks. The problem was fixed on 11/1/2011.

Subject:	GAN/MWR3C/M1 - 30-Ghz channel unstable
DataStreams:	ganmwr3cM1.b1
Description:	The 30-GHz channel was unstable between Dec 1 and Dec 5. Calibration was restored on Dec 9.
Measurements:	ganmwr3cM1.b1: Liquid water path best-estimate value, hourly mean(lwp) Water vapor, precipitable, column-integrated on isobaric grid, from RUC model(pwv) 30.0 GHz sky brightness temperature(tbsky30)

Subject:	GAN/MWR3C/M1 - Radiometer instability
DataStreams:	ganmwr3cM1.b1
Description:	The radiometer showed intermittent instability in the 30 GHz and 89 GHz channel. There was a calibration shift between Jan 4 and Jan 8 and a calibration instability between Jan 12 and Jan 20. It may be possible to recalibrate the data when a recalibration algorithm is developed.
Measurements:	ganmwr3cM1.b1: Liquid water path best-estimate value, hourly mean(lwp) Water vapor, precipitable, column-integrated on isobaric grid, from RUC model(pwv) 30.0 GHz sky brightness temperature(tbsky30) 89.0 GHz sky brightness temperature(tbsky89)
