Subject:	AWR/HTDMA/M1 - HT-DMA CPC zero counts
DataStreams:	awraoshtdmaM1.a1
Description:	HT-DMA CPC butanol flooding or contamination. CPC was showing zero counts. Intermittent counts from troubleshooting. No valid data.
Measurements:	awraoshtdmaM1.a1: Total concentration(total_concentration) scan_max_diameter_setting bin_width bin_center num_bins bin dry_diameter_setting dry_rh_setting Concentration of aerosol(aerosol_concentration) scan_min_diameter_setting

Subject:	AWR/HTDMA/M1 - Low instrument flows
DataStreams:	awraoshtdmaM1.a1
Description:	External vacuum was lost, affecting instrument flows. No valid data from the time period.
Measurements:	awraoshtdmaM1.a1: Total concentration(total_concentration) scan_time_setting scan_max_diameter_setting bin_width num_bins dry_diameter_setting dry_rh_setting sample_flow humid_rh bin_center bin atomizer scan_type scan_min_diameter_setting Concentration of aerosol(aerosol_concentration)

Subject:	AWR/HTDMA/M1 - No particle counts
DataStreams:	awraoshtdmaM1.a1
Description:	No particle counts after the instrument was turned on. Probably no butanol flow to the instrument or possibly a disconnected pump. No meaningful data saved.
Measurements:	awraoshtdmaM1.a1: Total concentration(total_concentration) Concentration of aerosol(aerosol_concentration)

Subject:	AWR/HTDMA/M1 - Intermittent zero counts
DataStreams:	awraoshtdmaM1.a1
Description:	Particle counts intermittently going to zero. Probably blocked butanol flow to the instrument or possibly internal air flow instability.
Measurements:	awraoshtdmaM1.a1: scan_time_setting scan_max_diameter_setting Total concentration(total_concentration) bin_width num_bins dry_diameter_setting dry_rh_setting sample_flow humid_rh bin_center atomizer scan_type scan_min_diameter_setting Concentration of aerosol(aerosol_concentration)
