BowEcho — A fast, free, native NEXRAD Level II radar viewer. Live super-resolution base data, dealiased velocity, dual-pol, derived severe-weather products, synced multi-pane, and vertical cross-sections — in a single small download. BowEcho decodes raw NEXRAD Level II data straight from the public AWS archive and live chunk feed (no account, no API key) and renders it with a fast CPU rasterizer that preserves the native super-resolution pixel pattern. It is built in Rust for speed: products switch instantly, panning stays fluid, and first pixels from a fresh volume arrive in well under a second on typical connections.
