SPDB is a simple data-base for storing meteorological data, tagging it with the observation time or model time, and retrieving it based on time. This page describes the conversion process.

+Thermodynamic soundings are important in RadxPid (and by extension, RadxRate) because temperature helps distinguish between liquid and frozen hydrometeors. Soundings can be ingested into RadxPid in three ways:
 * entered manually in the PID thresholds file - only one sounding is allowed.
 * estimated from model output (Grib2toMdv, Mdv2SoundingSpdb) - this is the preferred method.
 * observed sounding downloaded and converted from native format to SPDB - described below.
