Data sets

4 winters measurement data of specific surface area of solid precipitation particles including meteorological data and micro photo in Nagaoka S. Yamaguchi, M. Ishizaka, H. Motoyoshi, S. Nakai, V. Vionnet, T. Aoki, K. Yamashita, A. Hashimoto, and A. Hachikubo https://doi.org/10.1594/PANGAEA.907148

Short summary

The specific surface area (SSA) of solid precipitation particles (PPs) includes detailed information of PP. This work is based on field measurement of SSA of PPs in Nagaoka, the city with the heaviest snowfall in Japan. The values of SSA strongly depend on wind speed (WS) and wet-bulb temperature (T_w) on the ground. An equation to empirically estimate the SSA of fresh PPs with WS and T_w was established and the equation successfully reproduced the fluctuation of SSA in Nagaoka.
