Graham McIntire	5c9b43d619	Update analysis with solar time, refine algo.md time-of-day section ... Solar time (longitude/15) replaces fixed CDT/CST offset for time-of-day scoring. Correlation analysis shows dramatic improvement at higher frequencies: 24 GHz rho jumps from 0.056 (UTC) to 0.188 (solar), and 75 GHz corrects from spurious -0.39 to physically correct +0.24.	2026-04-01 09:02:57 -05:00
Graham McIntire	c12f8cf5ed	Use local solar time for time-of-day scoring, add PWAT factor and pressure refinements ... Score time-of-day per grid point using longitude/15 solar offset instead of hardcoded CST/CDT. Add PWAT as 10th scoring factor. Refine pressure thresholds. Update ML model and training pipeline to use local solar time.	2026-04-01 08:58:21 -05:00
Graham McIntire	8949920b7f	Add Nx/Axon/EXLA ML model skeleton for propagation prediction ... 13-feature feed-forward network (atmospheric + temporal + frequency). Includes build, init, predict, encode_features, save/load to disk. Model weights saved to priv/models/propagation_v1.nx (gitignored). Not yet trained — scaffolding only.	2026-03-31 16:26:34 -05:00
