Subject:	SGP/QCRAD/E20 - Failed tracker/improperly configured tracker
DataStreams:	sgpqcrad1longE20.c1, sgpqcrad1longE20.c2, sgpqcrad1longE20.s1, sgpqcrad1longE20.s2
Description:	On 1/15/2007 the E20 tracker failed due to weather. On 3/14 it was replaced but configured incorrectly (presumably the wrong lat/long). This wasn't discovered and corrected until 6/6/2007 1745GMT. All shortwave instruments dependent on proper tracker were affected. This includes measurements: downwelling shortwave diffuse and direct normal. Additionally, the global shortwave instrument have also been shaded during the second time range due to improperly set tracker. Discussed in instrument DQR D070927.1

Description:	Afer recovery from lightning strike the upwelling longwave SIRS Eppley PIR (UIR) had noise on both dome and case thermistor measurements. On 4/12/2006 techs replaced defective j-panel at base of tower. Noise didn't appear to have a bias but standard deviation went from 12-13 W/m2 during noisy period back to .75-1.5W/m2 after noise problem was eliminated. Described in instrument DQR D060403.4
