NAM CONUS GOES-Simulated Brightness Temperatures

GribStreamコード: namgoes218

公式リファレンス: NOAA NAM AWS Open Data registryとNCEP NAM productsを参照してください。

概要

NAM CONUS GOES-Simulated Brightness Temperaturesは、NAM CONUSフィードの衛星観測に近いシミュレーション出力です。

CONUSの主要プロダクトと同じ12 km Lambert格子で動きますが、通常のNAM気象フィールドではなく、大気上端の輝度温度シミュレーションを提供します。

雲頂診断、水蒸気プルーム、GOES画像との目視比較が必要で、同じNAM予報サイクルに結びついた衛星に近いフィールドを使いたい場合に向いています。

同じファミリーの通常の物理変数には、NAM CONUS Upper AirまたはNAM CONUS Surface Diagnosticsを使ってください。

SBT122 –Simulated Brightness Temperature for GOES 12, Channel 2 (K)
1 variant
NOAA GRIB2 Table 4.2-3-192

This field converts NAM-simulated top-of-atmosphere radiance into the equivalent GOES-12 channel 2 brightness temperature. It is used for model-to-satellite comparison rather than as a direct state variable.

  • Units: K.
  • Interpret it in the context of the channel's spectral response; it is not interchangeable with surface or cloud-top temperature.

SBT123 –Simulated Brightness Temperature for GOES 12, Channel 3 (K)
1 variant
NOAA GRIB2 Table 4.2-0-0

Simulated brightness temperature for GOES-12 channel 3 represents modeled radiance converted to an equivalent blackbody temperature. It supports satellite comparison and cloud diagnostics.

  • Units: K.

1 variant
NOAA GRIB2 Table 4.2-3-192

This field converts NAM-simulated top-of-atmosphere radiance into the equivalent GOES-12 channel 6 brightness temperature. It is used for model-to-satellite comparison rather than as a direct state variable.

  • Units: K.
  • Interpret it in the context of the channel's spectral response; it is not interchangeable with surface or cloud-top temperature.
