Peter Kuma Alpha sense OPC
Snow falling on Peter Kuma’s optical particle counter. The small grey case is an optical particle counter, it measures particles between 0.5 and 20 microns using the scattering of laser radiation. These are particles in the air, which might be dust, seasalt, or particles from plankton, on which cloud droplets can condense (form). So, helping answer the question of whether the presence of the particles in the air samples correlate with the clouds in the air that we are observing. Peter will use these observations to validate a NZ climate model for the Deep South Science Challenge.
