This form displays temperature and humidity graphs for the AMeDAS observation sites in Tokyo and Fuji.
The data can be retrieved from `https://www.jma.go.jp/bosai/amedas/data/point/44132/YYYYMMDD_HH.json`, where `HH` is one of `00`, `03`, `06`, ..., or `21`. The Japan Meteorological Agency appears to retain only the most recent 10 days of data. Therefore, I have been archiving the data in a PostgreSQL database since June 5, 2023, for the Tokyo site and since February 1, 2024, for the Fuji site.
