DataStreams:	twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:	Tracker inoperative because hit by lightning. Diffuse and direct normal shortwave irradiance incorrect during this time. LW downwelling data can have higher uncertainties under direct sun. Problem described in instrument DQR D090129.1
Measurements:	twpqcrad1longC3.s2: Radiation, shortwave, downwelling diffuse hemispheric irradiance, 1-min avg(down_short_diffuse_hemisp) Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) twpqcrad1longC3.s1: Radiation, shortwave, downwelling diffuse hemispheric irradiance, 1-min avg(down_short_diffuse_hemisp) Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) twpqcrad1longC3.c2: Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) Radiation, shortwave, downwelling diffuse hemispheric irradiance, 1-min avg(down_short_diffuse_hemisp) Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) twpqcrad1longC3.c1: Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal) Best Estimate Global Downwelling Shortwave Hemispheric Irradiance(BestEstimate_down_short_hemisp) Radiation, shortwave, downwelling diffuse hemispheric irradiance, 1-min avg(down_short_diffuse_hemisp)

Subject:	TWP/QCRAD/C3 - MFRSR data bad
DataStreams:	twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:	A refurbished system with a new logger was installed on 20100114. This was our first installation in the Southern Hemisphere. We had an unknown software bug, and initially the instrument was set up 180 deg off in an effort to get it to shade properly. This didn't work, and may have resulted in odd negative direct normal values. A software fix was made, and the instrument was set up correctly on March 11. From that point forward, data look OK. Some tests on best estimate global shortwave cannot be applied. BEGSW could be incorrect if MFRSR data used in tests or fits. Documented in instrument DQR D100520.2
Measurements:	twpqcrad1longC3.s2: MFRSR_direct_normal_broadband MFRSR_diffuse_hemisp_broadband MFRSR_hemisp_broadband twpqcrad1longC3.s1: MFRSR_direct_normal_broadband MFRSR_diffuse_hemisp_broadband MFRSR_hemisp_broadband twpqcrad1longC3.c2: MFRSR_hemisp_broadband MFRSR_direct_normal_broadband MFRSR_diffuse_hemisp_broadband twpqcrad1longC3.c1: MFRSR_hemisp_broadband MFRSR_direct_normal_broadband MFRSR_diffuse_hemisp_broadband

DataStreams:	twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:	On Jan 3rd approximately 1000GMT the effects of a tropical cyclone started affecting the installed radiometer measurements at ARM/TWP/C3(Darwin) - both SKYRAD and GNDRAD. On Jan 4th, 0740 GMT the GNDRAD was shutdown to avoid damage due to the close passing of this storm. GNDRAD was restarted Jan 7th 0515GMT.

DataStreams:	twpqcrad1longC3.c1, twpqcrad1longC3.c2, twpqcrad1longC3.s1, twpqcrad1longC3.s2
Description:	NIP is not working during these time periods as described in instrument DQRs D061214.1 & D081222.2. Direct normal irradiance is bad.

Subject:	TWP/QCRAD/C1 - LWdn ventilator failed
DataStreams:	twpqcrad1longC1.c1, twpqcrad1longC1.c2, twpqcrad1longC1.s1, twpqcrad1longC1.s2
Description:	LWdn flux may be questionable during this time. Described in instrument DQR D080826.3: During the time range specified the PIR2 output is questionable due to ventilator fan failure. Although the PIR is temperature compensated, data review indicates that the PIR2 didn't compare as well with PIR1. Typical differences during full sun are approximately 10 w/m2. During this time period differences of 10-14 W/m2 were noted.
Measurements:	twpqcrad1longC1.s1: Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) twpqcrad1longC1.c2: Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) twpqcrad1longC1.c1: Irradiance, longwave, downwelling, hemispheric(down_long_hemisp) twpqcrad1longC1.s2: Irradiance, longwave, downwelling, hemispheric(down_long_hemisp)
