 領域設定・統計値計算手順

統計値算出に用いた領域設定．

領域設定

領域は全て矩形領域で設定．境界となる緯度経度は下記:

• Domain-1: 日本全国 (24.0-46.0N, 120.0-150.0E)
• Domain-2: 沖縄・奄美 (24.0-30.0N, 122.0-132.0E)
• Domain-3: 九州・山口 (30.0-35.0N, 125.0-132.2E)
• Domain-4: 中国・四国 (32.0-38.0N, 132.2-135.0E)
• Domain-5: 近畿 (33.0-37.0N, 134.7-136.5E)
• Domain-6: 中部 (34.0-38.5N, 136.5-138.5E)
• Domain-7: 関東 (34.0-37.0N, 138.5-141.0E)
• Domain-8: 東北 (37.0-41.5N, 138.5-143.0E)
• Domain-9: 北海道 (41.5-46.0N, 138.5-146.0E)

パーセンタイル値の算出手順は下記:

• 領域内の全測定局(一般局，自排局など)を使用
• 同一時刻のすべての有効測定データのパーセンタイル値(10, 50, 90%値)を算出． より正確に表現すると，パーセンタイル値に相当する濃度順位(小数点以下四捨五入)を算出し， その順位の測定局の値を使用．つまり，すべて整数値である．
