Subject:	MAO/SASHE/M1 - Shadow band mis-aligned
DataStreams:	maosashevisM1.b1
Description:	The shadowband was not properly shading the diffuser. This precludes accurate separation of the direct and diffuse irradiance components. The total irradiances will be mostly unaffected, but direct normal, direct horizontal, and diffuse irradiances will be unreliable.

Subject:	MAO/SASHE/M1 - Mild band alignment issues affect irradiances except when sun is high in sky
DataStreams:	maosashevisM1.b1
Description:	Mild band misalignment makes separation between direct and diffuse irradiance suspect especially when the sun is not high in the sky. Outside the hours of 14-19 UT the data looks definitely bad. Use data within the 14-19 UTC interval with caution.

Subject:	MAO/SASHE/M1 - AOS mast shading SASHe collector
DataStreams:	maosashevisM1.b1
Description:	The SASHe collector was experiencing shading from the nearby AOS mast during the early morning. The time when the shadow falls across the SASHe varies somewhat but it occurs roughly in the 3 hour interval from 13:00-16:00 UT. It shows up as a direct normal irradiance dropping to zero or near zero. It is possible to distinguish this from actual cloud cover by examination of the MFRSR direct irradiance.

Subject:	MAO/PGH/PVC/SGP/SASHE/C1 - Reprocess: Stray light contamination at extreme wavelengths
DataStreams:	maosashevisM1.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.

Subject:	MAO/SASHE/M1 - Incorrect values
DataStreams:	maosashevisM1.b1
Description:	The SASHe uses a small USB "weather board" to report local atmospheric pressure as well as temperature and RH inside the instrument rack. This module is reporting static values. These measurements are being recorded for house-keeping purposes and do not have any direct impact on the measured spectra.
