Graham McIntire	5a9359191f	Replace wgrib2 with pure Elixir GRIB2 decoder for HRRR pipeline ... Eliminates the external wgrib2 C tool dependency that blocked HRRR processing. Implements Lambert Conformal projection, simple packing (Template 5.0), complex packing with spatial differencing (Template 5.3), and GRIB2 section parsing — enough to extract point values from HRRR grid data using only Elixir.	2026-03-29 18:43:43 -05:00
Graham McIntire	8bd0989fbe	Add HRRR model profile fetching for QSOs ... HRRR provides hourly 3km-resolution atmospheric profiles, filling the temporal gaps (12-hourly soundings) and spatial gaps (only 9 sounding stations) in our current weather data. - Add hrrr_profiles table and hrrr_queued flag on QSOs - HrrrClient fetches GRIB2 data via HTTP Range requests + wgrib2 - HrrrFetchWorker derives refractivity/ducting params via SoundingParams - QsoWeatherEnqueueWorker now also enqueues HRRR jobs - QSO show page displays HRRR section with collapsible profile - Dockerfile builds wgrib2 from source for production	2026-03-29 15:54:22 -05:00
Graham McIntire	6f16395f44	Add QSO import, solar indices, Oban workers, LiveView UI, and parallel weather import ... - Radio context with QSO schema and CSV import script (58K contacts) - Solar index schema, GFZ client, and daily Oban cron worker - LiveView dashboard with QSO table and weather correlation views - Parallelize weather import script using Task.async_stream (10 concurrent workers) - Replace sequential rate_limit sleeps with concurrency-based backpressure - Atomic progress counter for interleave-safe reporting	2026-03-29 13:04:55 -05:00
Graham McIntire	6489f08138	Add weather data schema, context, sounding params, and IEM ingestion ... Store surface observations (ASOS) and upper-air soundings (RAOB) alongside QSOs for atmospheric propagation correlation. Three new tables: weather_stations, surface_observations, and soundings with JSONB profiles and pre-computed derived parameters (refractivity, gradients, duct detection, stability indices). Includes IEM API client for historical data import and import script seeded with 95 ASOS + 9 sounding stations from PropCast coverage area.	2026-03-28 15:57:19 -05:00
