Subject:
ENA/HTDMA/C1 - Incorrect RH and air flow
DataStreams:enaaoshtdmaC1.a1
Description:
The HT-DMA internal RH sensor was sending out data in a format that was not correctly 
interpreted by the instrument software. This led the software to assume an incorrect RH 
reading and set the humid and dry air flows at incorrect values, affecting RH and other 
internal flows.
Suggestions: 
No valid measurements. Do not use the data for this period.
Measurements:enaaoshtdmaC1.a1:
  • Dry aerosol diameter size instrument setting(dry_diameter_setting)
  • Concentration of aerosol(aerosol_concentration)
  • Bin center value(bin_center)
  • Bin width(bin_width)
  • Dry aerosol particle relative humidity instrument setting(dry_rh_setting)
  • Minimum aerosol particle diameter instrument setting(scan_min_diameter_setting)
  • Humidified DMA scanning time instrument setting(scan_time_setting)
  • Atomizer calibration status(atomizer)
  • Sample flow rate(sample_flow)
  • Bin numbers for sweep measurements(bin)
  • Sampling mode scan type(scan_type)
  • Humid aerosol particle relative humidity(humid_rh)
  • Maximum aerosol particle diameter instrument setting(scan_max_diameter_setting)
  • Total scan concentration over all bins(total_concentration)
  • Number of bins stored in data block(num_bins)
