DMI HARMONIE DINI地表予報

GribStreamコード: dmidini

DMI DINI 2 meter temperature across the complete Northwestern Europe grid
DMI DINI 2 m temperature across its complete populated 2 km Northwestern Europe and North Atlantic footprint, with black country boundaries. This plot was generated from the dmidini dataset.

GribStreamで提供するデータ: dmidiniは、DMI Open DataのHARMONIE_DINI_SFから地表付近の日射、風、基本的な気象要素を選び、直近のデータだけを一定期間保持しています。

対象範囲: このページは決定論的なDINI地表プロダクトを扱います。DMIは、DINIの気圧面・モデル面、EPS平均・パーセンタイル・確率、アイスランドとグリーンランド向けのIGプロダクトも別に公開しています。これらは現在のdmidiniには含まれません。

風ベクトルに関する注意: DMIによるとU/V成分はLambert投影を基準にしています。GribStreamは元データの成分をそのまま提供するため、地球座標系の風向や別の座標参照系のベクトルを求める前に回転が必要です。

概要

DMI HARMONIE DINIは、デンマーク気象研究所（DMI）による北西ヨーロッパ向け高解像度地域予報です。DMIはDINIを、デンマーク、アイスランド、オランダ、アイルランドを覆うHARMONIE領域と説明しています。境界条件はECMWF、格子間隔は2 kmです。

GribStreamのdmidiniでは、まずアプリケーションで使いやすい地表フィールドを提供します。対象は日射、10 m・100 m風、雲、気温、湿度、視程、気圧、累積降水量です。IFSやGFSなどの全球モデルを、DINI領域のより細かな地域構造で補完できます。

特にエネルギーと現場運用に有用です。日射フィールドは短時間の日射状況の推定に使えます。100 mのU/V成分は、標準的な10 m風よりも風力タービンのハブ高度に近い風況を確認する材料になります。

DMIはパラメータごとに1つのソース名を使い、瞬間値、累積値、最大値、最小値を統計処理で区別しています。GribStreamでもその名前を維持します。たとえばdswrfでinfoが空なら、単位W/m^2の瞬間的な下向き短波放射フラックスです。info = "acc"なら、モデル実行開始からの累積エネルギーで、単位はJ/m^2です。累積値のうちdswrfとdirect-solar-exposureだけはリードタイム1 hから始まり、その他の累積フィールドにはDMIが提供するリードタイム0の値も含まれます。
