APIJoinable5/7Query nowOpen workbench Subscribe🇫🇷France

This API provides historical surface weather observation data derived from SYNOP messages circulated on the World Meteorological Organization's (WMO) Global Telecommunication System. It includes atmospheric parameters such as temperature, humidity, wind direction and force, and atmospheric pressure. The dataset is published via the open data portal of Métropole Aix-Marseille-Provence, France, and can be used for climate monitoring, meteorological research, and historical weather analysis at local and broader geographic scales.Données d'observations issues des messages internationaux d’observation en surface (SYNOP) circulant sur le système mondial de télécommunication (SMT) de l’Organisation Météorologique Mondiale (OMM).
