The specific surface areas (SSAs) of solid precipitation particles (PPs) in Nagaoka—a city in Japan experiencing the heaviest snowfall in the country—were measured for four winters (from 2013/2014 - 2016/2017). The data include meteorological data (air temperature, relative humidity, wind speed, air pressure and wet-bulb temperature) when SSAs of PPs were measured. The data also include micro photos of each PPs.
