Graham McIntire	c9112b9280	Recalibrate refractivity thresholds for HRRR gradient distribution ... Previous thresholds (-500 to -60) were calibrated for radiosonde data. HRRR profiles have coarser vertical resolution, with gradients clustering between -40 and -130 N/km (median -70). Nearly all grid points were falling through to the default score of 42, wasting the refractivity factor. New thresholds (-200 to -40) spread across HRRR percentiles.	2026-03-31 16:08:15 -05:00
Graham McIntire	2698f33cd3	Add propagation scoring algorithm with 9 weighted factors ... Implements BandConfig (data-driven thresholds for 8 bands) and Scorer module with humidity, time-of-day, TD depression, refractivity, sky cover, season, wind, rain attenuation, and pressure trend scoring. Composite score applies BandConfig weights (sum to 1.0) across all factors, producing 0-100 score per band. 10 GHz uses beneficial humidity/ducting model; 24 GHz+ uses harmful absorption model.	2026-03-30 16:57:38 -05:00
