NAM CONUS GOES-Simulated Brightness Temperatures

GribStream Code: namgoes218

Description

NAM CONUS GOES-Simulated Brightness Temperatures is the simulated-satellite slice of the North American Mesoscale (NAM) CONUS feed. It runs on the same 12 km Lambert grid as the core CONUS products, but carries top-of-atmosphere simulated brightness temperatures instead of the usual weather-state inventory.

Use it when you need cloud-top, moisture plume, or satellite-analogue diagnostics tied directly to the NAM forecast cycles without post-processing the full physics fields yourself. For the underlying forecast-state feeds, pair it with NAM CONUS Upper Air or NAM CONUS Surface Diagnostics.

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.

SBT126 –Simulated Brightness Temperature for GOES 12, Channel 6 (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.
