Graham McIntire	4e2d74e21c	Build wgrib2 in Docker with cached build stage ... Add a separate wgrib2-builder stage that compiles wgrib2 from source. Docker layer caching means this only builds once — subsequent deploys reuse the cached layer. The binary is copied into the final runtime image. Also fixed wgrib2 path lookup to be runtime instead of compile-time so it works in the Docker build pipeline.	2026-03-31 08:55:09 -05:00
Graham McIntire	b7446e83f5	Use wgrib2 for HRRR grid extraction (7s vs 80+ minutes) ... Add Wgrib2 module that shells out to wgrib2 binary for fast GRIB2 grid extraction using -lola (nearest-neighbor to regular lat-lon grid). Falls back to pure-Elixir decoder if wgrib2 is not installed. Also: parallel GRIB2 range downloads, merge adjacent byte ranges, skip corrupt messages instead of failing, pressure fetch is optional.	2026-03-31 08:33:29 -05:00
