AtmosVue™30の仕様の詳細(実際の意味)

atmosvue™30の仕様の詳細(実際の意味)

AtmosVue™30, のような気象センサーの仕様書を見ると、多くの数字や専門用語が記載されているのが一般的です。例えば、以下のような内容です: 現在の天気出力 背景輝度測定範 動作温度範囲 しかし、これは実際何を意味するのでしょうか? このブログ記事では、AtmosVue 30 の主な仕様を分析し、その内容を簡単な言葉で説明します 背景 はじめに、AtmosVue 30は3つの独立したセンサー: CS125 現在天気・視程センサ,  CS140 背景輝度センサ, and the HygroVue™5 デジタル温湿度センサ で構成されていることをご留意ください。この記事ではAtmosVue 30のスペックシートに関する情報を共有しますが、AtmosVue 30を構成するセンサーのいずれかについて同様の情報をご希望の場合は、下記にコメントをお寄せください。 AtmosVue 30の主な仕様 報告される最大可視性 AtmosVue 30 の場合、報告される最大視程は 100 km (62.1 マイル) です。 報告される最大視程は、現在の気象条件下で、空港にいる人(パイロット、航空管制官、またはその他の航空利用者)が地上 2 メートル(6.6 フィート)の高さで水平にどれだけ遠くまで見通せるかを示します。 背景輝度測定範囲 AtmosVue 30 の場合、背景輝度の測定範囲は 0 ~ 45,000 cd/m 2です。 背景の輝度は、滑走路の照明と背景の空周辺光レベルとのコントラストの強さを理解するのに役立ちます。これは、パイロットが飛行場に着陸するときにどれだけ遠くまで見通せるかを決定する重要な測定値です。 背景の周囲光レベルは、国際照明委員会(CIE)の分光感度を用いて、人間の目で見るのと同じ波長で測定されます。言い換えれば、人間が私たち人間と同じ波長の光を「見ている」ということです。 背景輝度を用いることで、あらゆる光条件、特に低照度または低コントラスト条件における視程計算方法をどのように調整する必要があるかを判断できます。カンデラ/平方メートル(cd/m 2)で測定される背景輝度を、より大規模な計算における他の測定値と組み合わせることで、航空機の視程を決定するのに役立ちます。 現在天気出力 AtmosVue 30 の場合、1 つの出力で 57 個の SYNOP 現在の気象コードと、関連する気象飛行場レポート (METAR) および国立気象局 (NWS) の現在の気象コード、および過去の気象コードが提供されます。 世界気象機関(WMO)は、気象情報を複数の言語に翻訳することなく国際的に伝達するための標準化された手法を開発しました。この通信システムでは、SYNOPと呼ばれる数値コードが一部使用されています。SYNOPコードは一定の頻度(通常は3時間または6時間ごと)で送信され、その地点における現在の重要な気象現象をすべて記述できます。例えば:... 続きを読む
