Scans update every 5 minutes and are processed into the ARAMIS mosaic within seconds of each scan cycle — no smoothing, no averaging delay. From Arcachon's position on the map, the radar composite shows coverage across the surrounding region continuously, including neighboring departments and cross-border coverage where relevant.
