Storing soundings in SPDB

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.

Model Output

TTAA/TTBB

University of Wyoming soundings.

TTAA/TTBB format. 


NWSsoundingIngest -params NWSsoundingIngest.test -debug -f /path/to/data/NWS_soundings/20210101_000000.denver_soundings.txt
SpdbQuery -url /path/to/data/NWS_soundings/spdb -mode interval -start "2021 01 01 00 00 00" -end "2021 02 01 00 00 00"


In the RadxPid params files the PID_sounding_location_name would be set as "72469", the Denver station ID. (In Mdv2SoundingSpdb.gfs, set with $(RADAR))
