Enhance PB2NC to derive PBL and CAPE from aircraft-based soundings

JohnHalleyGotway commented 1 year ago

Describe the Enhancement

This issue was raised via METplus Discussion dtcenter/METplus#1860 and was discussed during the METplus NOAA User telecon on 4/3/2023. @PerryShafran-NOAA notes that existing VSDB code does derive PBL and CAPE from aircraft sounding data. However the logic is complicated since the derivation combines model analysis-derived moisture data with aircraft point observations. So that'd require PB2NC to combine gridded model data with point observations.

This task is to collaborate with @PerryShafran-NOAA, @LoganDawson-NOAA, and @jason-english to determine if/how the PB2NC tool should be enhanced to derive PBL and/or CAPE from aircraft sounding data.

Many questions remain on how to perform those derivations and how to validate the quality of the derived values.

Time Estimate

@DanielAdriaansen will reach to @PerryShafran-NOAA to discuss this work further.

Removed from the 12.0.0 release during the METplus NOAA telecon on 6/10/24 since aircraft obs will not be included in EVS v2.
