truestar inc. weather 3 times/ everyday
This dataset, which includes climate normal data for the next one week, was processed by truestar based on the “Prefectural Weather Forecast” data published by the Japan Meteorological Agency.
Climate normal data is published by the Meteorological Office together with weekly weather forecast data.
The climate normal is the average of the temperature (in the unit of 0.1°C) and precipitation (in the unit of 1 mm) observed at the forecast location over the last 30 years (1991-2020) and is updated once every 10 years.
Using FORECAST_AREA_CODE, this dataset can be easily combined with other data such as JMA_FORECAST_WEATHER_1WEEK for analysis.
