Good H. Coe G. McFiggans g.mcfiggans@manchester.ac.uk Centre of Atmospheric Science, School of Earth Atmospheric and Environmental Sciences, University of Manchester, Manchester, UK The methodology for the operation and calibration of hygroscopicity tandem differential mobility analyser (HTDMA) and cloud condensation nuclei counter (CCNc) for size resolved measurements of aerosol water uptake are presented. A state of the science aerosol thermodynamic model is used to benchmark the performance of the instruments. The performance, calibration and operation of the instruments is then demonstrated in the field. Allan, J. D., Baumgardner, D., Raga, G. B., Mayol-Bracero, O.
