Overview
This dataset contains daily-collected weather forecasts for up to seven days ahead for all the meteorological observatories in Japan, published by the Japan Meteorological Agency (JMA) at https://www.jma.go.jp/bosai/forecast/. We collect, structurize, and accumulate the prediction since the page is overridden whenever the information is updated.
The data is automatically updated daily using GitHub Actions. Since the actual forecasts are published multiple times a day, we set up the column from_hour which represetnts the announced time.
Further details are also available at note.com/jniimi/n/n06d3423bbbbf (Japanese only).
Usage
This dataset can be utilized across a wide range of research fields. While it is primarily valuable in the natural sciences, it can also be applied to social sciences, such as the behavioral modeling and prediction.
