French River Temperature Readings from Continuous Sensors (Hub'Eau)

hubeau/river-temperature

Water temperature readings from automatic sensors in metropolitan French rivers: station and commune, river, date and time, temperature in degrees Celsius and qualification. Choose how many readings to return (1 to 100), optionally for one station code, and optionally newest first. Without the sort option the service returns the oldest readings first. Only about fifty of the roughly 760 stations are still in service. Data from Hub'Eau, producers OFB / BRGM / SCHAPI-Vigicrues, Licence Ouverte Etalab; served by Eden Engine; not an official Hub'Eau product.
