Subject:	AWR/TSI/M1 - polar night
DataStreams:	awrtsiskycoverM1.b1
Description:	The sun did not rise above 3 deg elevation, required for image processing, due to the polar night.

Subject:	AWR/TSI/M1 - Collection
DataStreams:	awrtsiskycoverM1.b1
Description:	The scheduled task that starts the software each day at 12:58, was not enabled. This resulted in intermittent loss of data.
Measurements:	awrtsiskycoverM1.b1: qc_sun_strength region_zenith_count_thin qc_region_sun_count_opaque region_zenith_count time_offset count_sky region_horizon_count count_box qc_region_horizon_count_thin solar_altitude Altitude above mean sea level(alt) sun_strength count_opaque count_thin qc_solar_azimuth East longitude(lon) qc_count_sub_proczen qc_count_sub_horz qc_region_zenith_count region_sun_count_opaque qc_count_box region_horizon_count_opaque qc_percent_opaque Cloud amount, thin (percent)(percent_thin) count_sub_horz qc_count_sky count_unknown qc_count_opaque region_sun_count_thin qc_region_zenith_count_opaque Cloud amount, opaque (percent)(percent_opaque) North latitude(lat) qc_time time region_zenith_count_opaque count_mask count_sub_proczen qc_region_zenith_count_thin region_horizon_count_thin base_time qc_region_sun_count qc_count_unknown qc_region_horizon_count Sunshine Meter(sunny) qc_percent_thin qc_solar_altitude qc_region_sun_count_thin qc_region_horizon_count_opaque qc_sunny qc_count_thin region_sun_count solar_azimuth qc_count_mask

Subject:	AWR/TSI/M1 - Shadowband misalignment
DataStreams:	awrtsiskycoverM1.b1
Description:	The mirror became loose from the shaft, probably due to high winds and cold temperatures, so that the shadowband was not masking the sun. The mirror was secured and the shadowband realigned.
Measurements:	awrtsiskycoverM1.b1: count_sky Cloud amount, opaque (percent)(percent_opaque) count_opaque region_horizon_count_opaque Cloud amount, thin (percent)(percent_thin) count_thin region_zenith_count_opaque region_zenith_count_thin region_sun_count_opaque region_sun_count_thin region_horizon_count_thin

Subject:	AWR/TSI/M1 - Snow infiltration
DataStreams:	awrtsiskycoverM1.b1
Description:	The lid of the TSI enclosure was not secured properly on 9/23 allowing snow infiltration which caused the mirror control board to malfunction on 10/12 so the shadowband did not mask the sun. The TSI was shutdown on 10/14, brought inside on to thaw and dry out, and reinstalled on 10/15.
Measurements:	awrtsiskycoverM1.b1: Cloud amount, opaque (percent)(percent_opaque) count_opaque region_horizon_count_opaque Cloud amount, thin (percent)(percent_thin) count_thin region_zenith_count_opaque region_zenith_count_thin region_sun_count_opaque sun_strength region_sun_count_thin region_horizon_count_thin
