Subject:	TWP/MWR/C2 - Incorrect data
DataStreams:	twpmwrlosC2.b1, twpmwrtipC2.a1
Description:	The data quality for this instrument noticeably deteriorated starting in June 2013 although the beginning of this DQR is an estimated start of the problem. The tip curve data are degraded and the elevation readings shoe large differences on the two sides of the scan. The quality of the resulting zenith brightness temperatures is therefore degraded. The resulting LWP and PWV are incorrect.

Subject:	TWP/MET/C1 - PWD reporting low precipitation
DataStreams:	twpmetC1.b1
Description:	The PWD reported much lower precipitation values than co-located sensors. A mud wasp nest was removed from the lens. This may have affected visibility values as well.
Measurements:	twpmetC1.b1: pwd_precip_rate_mean_1min PWD 1 minute mean visibility(pwd_mean_vis_1min) pwd_err_code pwd_pw_code_inst pwd_cumul_rain pwd_pw_code_15min pwd_pw_code_1hr PWD 10 minute mean visibility(pwd_mean_vis_10min)

DataStreams:	twpmwrlosC1.b1, twpmwrtipC1.a1
Description:	Data are intermittent during this time. Users should avoid using these data
