Flows, water levels and Hydro-Québec weather data

Geolocated hydrometeorological data collected at Hydro-Québec gauging and weather stations:River dischargeWater levelPrecipitation type (rain, snow) and accumulationSnowpack and water equivalentInstantaneous air temperatureInstantaneous relative humidity and average relative humidity Wind speed and direction at 2.5 m (some at 10 m)MethodsRiver dischargeRiver discharge is calculated based on water levels measured upstream and downstream of a river.Water levelData on water levels are collected remotely at Hydro-Québec hydrometric stations every 15 minutes. They are then transmitted by satellite to our systems and recorded.Precipitation Data on precipitation are collected hourly at Hydro-Québec meteorological stations. They are then transmitted by satellite to our systems and recorded. Data on accumulated precipitation and precipitation type are collected at Hydro-Québec meteorological stations every 15 minutes. They are then transmitted by satellite to our systems and recorded.Snowpack and water equivalentThe gamma monitoring (GMON) sensor continuously collects data on snowpack and water equivalent.Water equivalent data are collected at meteorological stations every six hours. They are then transmitted by satellite to our systems and recorded.Snowpack data are collected hourly at meteorological stations. They are then transmitted by satellite to our systems and recorded.TemperatureTemperature data are collected hourly at Hydro-Québec meteorological stations. They are then transmitted by satellite to our systems and recorded. HumidityData on instantaneous relative humidity are collected hourly at meteorological stations. They are then transmitted by satellite to our systems and recorded.WindData on wind speed and direction at 2.5 m from the ground are collected at Hydro Québec meteorological stations every 15 minutes. They are then transmitted by satellite to our systems and recorded.UnitsRiver discharge: m³/sLevel: mTotal precipitation: mmSnowpack: cmWater equivalent (of snowpack): cmMaximum temperature: °CMinimum temperature: °CRelative humidity: %Average wind speed at 2.5 m: km/hWind direction at 2.5 m: °Additional informationUpdate frequency: twice dailySampling frequency: hourly.Geographic coverage: network of Hydro-Québec hydrometeorological stations Temporal coverage: 10 daysCreated: 2021-06-12Notices and conditions of use: The information provided represents raw data.
