Description: | During the night of 11/05-06 2004 the tracker failed at this location. During CM on 12/01, power cycling returned the tracker to service. However, tracker was not properly tracking in the AM. Tracker failed again sometime near 01/01/2005. CM reloaded the tracker program and realigned the tracker on 01/26/2005 1600GMT correcting the problem. Documented in instrument DQR: D041206.1 |

Subject: | SGP/QCRAD/E10 - Missing surface met data |
DataStreams: | sgpqcrad1longE10.c1, sgpqcrad1longE10.c2 |
Description: | Surface meteorological data were missing during these time periods. Met data is used in a variety of quality control checks described below. Air temperature data is needed for tests on LW up and LW down pyrgeometer case and dome temperatures, and tests on the irradiances from upwelling LW/SW and downwelling LW. The Rayleigh limit diffuse radiation test is based on surface pressure. There were no instrument DQRs on this problem at the time this report was submitted. |

Description: | Possible main power problem made may have caused the tracker to fail. Attempts to restart the old tracker, subsequent replacement and lack of spares contributed to incorrect data from the NIP (short_direct_normal datastream) and 8-48 (down_short_diffuse_hemisp datastream) until the time of site decommissioning. This facility was decommissioned and maintenance efforts ceased 10/1/2009. The instrument was removed from service 12/04/2009. Documented in instrument DQR D090609.1 |

DataStreams: | sgpqcrad1longE10.c1, sgpqcrad1longE10.c2, sgpqcrad1longE10.s1, sgpqcrad1longE10.s2 |
Description: | From about 950721 to about 970204 (19:12 GMT) the wrong calibration factor was applied to the NIP at site E10. The calibration factor that was used was 1.00E-06 Volts/(W m^2). The correct calibration factor is 8.338E-06 Volts/(W m^2). Thus the calibrated NIP values found in the netCDF files are too large by a factor of 8.338. Documented in instrument DQR D970213.1 |
