It uses electrostatic classifiers to select particles of a particular electrical mobility diameter, conditions them (using a thermodenuder and humidifier) and re-measures the particle diameter. The VH-TDMA is made up of three purpose built electrostatic classifiers and two condensation particle counters (CPCs). One TSI 3010 CPC and one TSI 3787 CPC. The pre-classifier (used to select particles of a particular dry diameter) most commonly cycled between measuring 40, 100 and 150 nm diameter particles during IN2016_v02. For short periods other particle diameters were selected (20, 30, 60,80 nm), to examine features in the ambient size distribution. The thermodenuder was set to 250 °C for the majority of IN2016_v02, with short periods at other temperatures (150°C, 200°C). The relative humidity of the H-SMPS was set to 90% RH for most of the voyage, however it was periodically lowered for size calibration scans and to measure the deliquescence RH for ambient particles. The sample was passed through a nafion drier and inlet RH logged to ensure that dry particle diameter was selected i.e. RH < 30%, the efflouresence RH for common marine salts.Progress Code: onGoingMaintenance and Update Frequency: asNeededStatement: ACQUISITION SOFTWARE: SMPS raw data file (.S80), obtained using Aerosol Instrument Manager (AIM).

Brief description

The VHTDMA was constructed at QUT for measurement of ultrafine aerosol volatility and hygroscopicity. It uses electrostatic classifiers to select particles of a particular electrical mobility diameter, conditions them (using a thermodenuder and humidifier) and re-measures the particle diameter. The VH-TDMA is made up of three purpose built electrostatic classifiers and two condensation particle counters (CPCs). One TSI 3010 CPC and one TSI 3787 CPC.

The pre-classifier (used to select particles of a particular dry diameter) most commonly cycled between measuring 40, 100 and 150 nm diameter particles during IN2016_v02. For short periods other particle diameters were selected (20, 30, 60,80 nm), to examine features in the ambient size distribution. The thermodenuder was set to 250 °C for the majority of IN2016_v02, with short periods at other temperatures (150°C, 200°C). The relative humidity of the H-SMPS was set to 90% RH for most of the voyage, however it was periodically lowered for size calibration scans and to measure the deliquescence RH for ambient particles. The sample was passed through a nafion drier and inlet RH logged to ensure that dry particle diameter was selected i.e. RH < 30%, the efflouresence RH for common marine salts.

DATA PROCESSING:
This is raw data, corrections for DMA, size (Kelvin) and shape factor effects as outlined in Gysel et al. (2009), Modini et al. (2010) and Cravigan et al. (2015) and other quality control measures will be applied to SMPS data. This will be undertaken by QUT in 2016. Periods of missing data occur during calibration scans. Pollution events (largely from the ship itself) are included in this data. Pollution flagging using black carbon, particle number concentrations etc. will be undertaken as a part of data processing.
