Overview
Thermodynamic soundings are important in RadxPid 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.
The second and third method both require data or output to be converted to an SPDB database file, which is a non-gridded file. This page describes how to convert Grib2 and TTAA/TTBB files to SPDB.
