Joseph Ulanowski

Biography

I spent most of my research career at University of Hertfordshire, from which I formally retired in 2019. However, since then I have been continuing my collaboration with a number of institutions in the UK and overseas.

My interest in polar research began in 2016 with the development of a technique for semi-remote sensing of ice precipitation (“diamond dust”) at Summit station, Greenland (Goerke et al. 2017 – see also a time-lapse video). I started working with colleagues in the BAS Atmosphere, Ice and Climate team around 2017, when I provided them with novel cloud sondes developed at Hertfordshire for an ODA-funded measurement campaign in the Himalayas.

Research interests

My areas of interest are light scattering, characterization of aerosols, radiative properties of cirrus clouds, optical techniques for in situ and remote cloud sensing, optical instrument development, particle trapping and micromanipulation techniques. One of the highlights of my career has been the development of realistic ice analogues, which have been used to study the light scattering properties of atmospheric ice crystals, and for the characterization and calibration of various cloud probes.
