Spatial + temporal nearest-RAOB lookup (defaults to 300 km / ±3 h) joining weather_stations → soundings. Returns the full sounding row so callers can read the derived ducting_detected / min_refractivity_ gradient fields that HRRR's pressure-level product systematically under-reads for thin surface ducts. Prep for the path-calculator enrichment: a sounding within range at the path midpoint gives an independent duct signal to cross-check the nine HRRR samples already taken along the path. |
