Plain Language Summary: The relationships between the radar reflectivity factor for horizontal polarization (Zh) at X-band and liquid-equivalent snowfall rate (R), of the form Zh = B R1.67, are presented for six hydrometeor classes of solid precipitation. Snow aggregates demonstrated a stronger or weaker backscattering than graupel of the same R depending on the riming degree and types of constituent ice crystals in the X-band.
