instrument description
	"The NCSU HTDMA was operated at a sheath-to-sample flow ratio of 5:1 L min−1. The HTDMA was configured to measure hygroscopic growth factors of dry particles with mobility diameters of D = 15, 20, 30, 40, and 50 nm at RH > 75%. A complete cycle for all diameters took ~30 minutes. A sample line (¼” conductive tubing) slightly top of the tower, brought aerosol inside the trailer at 2.5 L min-1, where it was distributed between NCSU RDMA (1.5 L min-1) and NCSU HTDMA (1 L min-1) lines. The sample line was dried with three silica-gel driers in series, and then neutralized with X-ray neutralizer. The sample line entered DMA1 (operated as an electrostatic classifier). Monodisperse particles with certain fractions were humidified with temperature controlled Nafion membrane immersed in water before entering DMA2 (operated in scanning mobility particle sizer). Please contact mdpetter@ncsu.edu for further information."
		
quality assurance and quality control 
 	"The 10 Hz raw data from the NCSU HTDMA were acquired using a custom data acquisition system that logged time at UTC. Data during general instrument maintenance, data outages during storms, and suspected instrument malfunction, and during HTDMA calibrations are removed. Calibrated RH values are given below. Examples of general instrument maintenance are HTDMA calibrations, and renewing silica gels in the dryers. A dilute ammonium sulfate particles were used to calibrate the HTDMA. Example of instrument malfunction are power outages and water build up in the dryers that needs to be replaced.

Data reduction procedures for HTDMA are based on DMA theory; the inversion procedures were applied to the raw data according to Petters (2018, 2021).  
The growth factors (gf) retrieved from HTDMA were converted into kappa values using the weekly average of the RH calibrations. The calibration plot for the whole campaign includes the mean +-standard deviation of the calibrated RH.
