What form of precipitation starts as snow, melts in a warm layer, then refreezes near the ground because surface air is very cold?

Explanation:
Precipitation type is determined by temperature changes as air moves. If snow falls into a warm layer, it melts into rain. When that rain then passes through a very cold layer near the ground, it refreezes into small ice pellets before reaching the surface. Those ice pellets are sleet. This differs from freezing rain, which stays liquid until it hits surfaces and freezes on contact, and from hail, which forms in strong updrafts inside storms. So the described sequence matches sleet.
