CAMS全球大気組成予報

GribStreamコード: camsglobal

CAMS Globalのネイティブ全球格子における550 nm全エアロゾル光学的厚さと国境線
2026年7月11日00 UTC初期値、予報時間120 hのCAMS Global 550 nm全エアロゾル光学的厚さを、0.4度ネイティブ全球格子の405,900セルすべてについて表示し、国境線を重ねています。この図はcamsglobalデータセットから生成しました。

公式ソース: CAMS全球大気組成予報はCopernicus Atmosphere Monitoring Serviceが提供し、ECMWFが運用しています。現行資料では、2026年5月12日に運用開始したIFS Cycle 50r1が約40 kmの全球プロダクトに使われています。

GribStreamでの範囲: camsglobalは、高速アクセス可能な地表面または気柱全量の大気組成37フィールドを収録します。初期リリースでは、重複する気象変数と多層の化学場を意図的に除外しています。00・12 UTCサイクルを120 hまで毎時提供し、直近5日分を保持します。

出典表示: 加工した表示にはCAMS指定の次の表記を保持しています。Contains modified Copernicus Atmosphere Monitoring Service Information 2026. Neither the European Commission nor ECMWF is responsible for any use that may be made of this information.

概要

CAMS Globalは、物質を運ぶ気象場だけでなく、大気中の化学成分とエアロゾルそのものを予報します。運用システム全体では、対流圏の反応性微量気体56種、成層圏オゾン、7種類のエアロゾルを扱います。ECMWF IFSにCAMSの排出、化学反応、輸送、エアロゾル微物理、沈着、除去過程を組み込んでいます。

初期状態は、直前の予報と衛星観測を4次元変分法で組み合わせて作られます。気温、風、降水だけでは捉えられない大気質、黄砂、煙、エアロゾル負荷を判断するときに、大気組成変数が重要になります。

GribStreamの初期リリースは、高速アクセス可能な37フィールドに絞っています。地表面のpm1、pm2p5、pm10、5波長の全光学的厚さと550 nmでの成分別光学的厚さ、気体・汚染物質の気柱全量、全天候時と晴天時の2種類の生物学的実効UV線量率を収録します。

ソースの名称と単位を維持します。CAMSの粒子状物質はkg/m^3です。GribStreamの式で1e9倍すると、一般的なマイクログラム毎立方メートルに換算できます。AODは無次元、気柱全量の質量はkg/m^2です。2つのUVフィールドはW/m^2単位の瞬時線量率で、UV Indexそのものではありません。40倍するとUVIになります。

CAMSはモデル予報であり、地域の規制監視網を置き換えるものではありません。0.4度格子は全球輸送と大気組成の把握に適していますが、道路単位の曝露推定には向きません。tc_VSO2は火山性二酸化硫黄の気柱負荷を示しますが、噴煙高度は示しません。

座標ごとの時系列には/api/v2/camsglobal/timeseries、予報サイクル単位または格子抽出には/api/v2/camsglobal/runsを使います。気象場はIFS、全球大気組成のアンサンブル比較はGEFS Chem、米国の高解像度地域大気質はNOAA AQMと組み合わせられます。
