WINTRE-MIX: Manual Hydrometeor Observation Reports. Version 1.0

Manual observations were conducted to support the Winter Precipitation Type Research Multi-Scale Experiment (WINTRE-MIX) during 11 intensive observation periods (IOPs) between 01 Feb – 15 March 2022. Manual observations primarily include precipitation type, ice accretion thickness, and snowboard sampling measurements. These observations were conducted by research teams from the University at Albany, University of Colorado Boulder, Université du Québec à Montréal (UQAM), and McGill University. The research teams usually collected their manual observations throughout each IOP. Typically, the manual observations were conducted every 10 minutes at the same site as the soundings.
