This dataset contains radar measurements, as well as ground-based observations of hydrometeors collected in the Gangwon-do province in South-Korea. It includes observations from an X-band dual-polarisation Doppler radar, a W-band Doppler cloud profiler, a multi-angle snowflake camera and a two-dimensional video disdrometer. Classifications of hydrometeor types based on dual-polarisation measurements and snowflake photographs are also available. The dataset covers the period from 15 November 2017 to 18 March 2018 and features nine precipitations events with a total accumulation of 195 mm of equivalent liquid precipitation.
