このデータセットはアメリカの汚染問題を扱っています。アメリカEPAはアメリカの汚染状況を十分に記録していますが、すべてのデータをダウンロードし、データサイエンティストが興味を持つ形式で整理するのはとても苦痛なことです。そこで、2000年から2016年まで、私は4種類の主要な汚染物質（二酸化窒素、二酸化硫黄、一酸化炭素、オゾン）を毎日収集し、それらをきちんとCSVファイルにまとめました。
内容
合計28のフィールドがあります。4種類の汚染物質（NO2、O3、SO2、O3）それぞれに5つの特定の列があります。観測総数は140万を超えています。このカーネルはこのデータセットについて素晴らしい紹介をしています！
特定の列に関する観測結果については、データタブの列メタデータを参照してください。
