一応任意のアメダス観測所の計測データを取得できるようにしてみました。あまり使う予定はありませんが。
misohena/el-jma: Emacs Interface for Japan Meteorological Agency Data
使い方。
まずはアメダスの観測所番号を調べます。 jma-amedas-read-amedas-code 関数で補完付きの入力ができるようになっているのでそれを使います。
(require 'jma-amedas) (jma-amedas-read-amedas-code)
番号が分かったら jma-amedas-point-latest に渡すだけです。
(jma-amedas-point-latest ;;最新のデータを取得 "44112");;八王子
結果は次のようになります。

一応アクセッサがあるのでそれを使うと楽にデータを取り出せます。
(let* ((amedas-code "44112") (sample (jma-amedas-point-latest amedas-code))) (format "%sの%sの気温は%s℃、降水量(前1時間)は%smmです" (jma-amedas-point-name (jma-amedas-point amedas-code)) (format-time-string "%Y-%m-%d %H:%M" (jma-amedas-sample-time sample)) (or (jma-amedas-sample-temp sample) "-") (or (jma-amedas-sample-precipitation1h sample) "-")))
"八王子の2022-02-26 14:10の気温は12.6℃、降水量(前1時間)は0.0mmです"
取り出せる情報は設備の種類によって異なります(気象庁 | アメダスあたりを参照のこと)。
また、計測値の品質に問題がある場合はnilを返します。生データの配列(上の例だと(temp . [12.6 0])等)の二番目の要素が品質を示す値で、0のとき正常を意味します。
期間を指定して取得することも可能です。

1度のアクセスで10分毎の計測データが3時間分まとめて取得できるので、必要なだけアクセスして結果をつなぎ合わせてから不要な部分をカットしています。サーバへのアクセス頻度が高くなりがちなのでご注意ください(とは言え気象庁の観測データ一覧ページで行っていることと同じではあります)。
過去数日程度のデータしか取得できないようです。それ以前のデータは気象庁｜各種データ・資料のあたりから取得しましょう。
