Rain data for Obernai, France comes from Météo-France — the French national meteorological service — via its ARAMIS radar network of 31 Doppler stations covering metropolitan France. Most stations operate in dual-polarization mode, meaning the radar returns are processed for both liquid and frozen precipitation and deliver more accurate rainfall estimates than single-polarization systems. Scans update every 5 minutes and are processed into the ARAMIS mosaic within seconds of each scan cycle — no smoothing, no averaging delay. From Obernai's position on the map, the radar composite shows coverage across the surrounding region continuously, including neighboring departments and cross-border coverage where relevant.
