The WeIzmann Supercooled Droplets Observation on Microarray (WISDOM) is a new microfluidics setup for studying atmospheric ice nucleation in a cold stage technique. The droplets production using microfluidics technology provides an array of hundreds of isolated monodisperse picolitre droplets. The array is cooled under a microscope and monitored continuously to achieve frozen fractions, active sites densities, and nucleation rates
