Subject: MAO/PGH/PVC/SGP/SASHE/C1 - Reprocess: Stray light contamination at extreme wavelengths
Affected Datastreams: maosashenirM1.b1
Description The irradiance measurements at near the limits of the spectrometer wavelength ranges are subject to contamination from stray light within the spectrometer itself. This affects not only the basic measurement, but also can affect the calibration such that reported values may be either higher or lower than actual. Typically, this yields a high bias for measurements at the low wavelength limit and a low bias at the high wavelength limit. This causes opposite effects for AOD with a low bias at low wavelength and a high bias for high wavelengths.
Measurements
  • direct_normal_spectrometer_nir (Direct normal solar irradiance, Si CCD spectrometer)
  • diffuse_hemisp_spectrometer_nir (Diffuse hemispheric irradiance component, Si CCD spectrometer)
  • direct_horizontal_spectrometer_nir (Direct horizontal solar irradiance from Si CCD spectrometer)

Subject: SGP Site Power Outage Due to Winter Storm
Affected Datastreams: sgpirt200msE13.a1
Description On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use.

Subject: SGP/SASHE/C1 - Temperature controller disabled
Affected Datastreams: sgpsashenirC1.b1
Description After servicing of the SASHe on Dec 20, 2013 a temperature controller was left in a stand-by mode. The situation was corrected slightly before 20:00 UT on Jan 14, 2014. Both the "vis" and "nir" spectrometers have some potential for temperature sensitivity but the impact should not be severe given that the system is housed within a climate controlled building and the temperature gradients are small.
