GribStream

NOAA AI Global Forecast System Surface (AIGFS Surface)

Codice GribStream: aigfssfc

Descrizione

AIGFS Surface è la linea deterministica globale NOAA/NCEP basata su IA per campi vicino alla superficie. Porta la famiglia GraphCast dentro un flusso operativo più adatto a prodotti ricorrenti.

In GribStream aigfssfc espone campi come vento a 10 m, temperatura a 2 m, pressione media al livello del mare e precipitazione accumulata su griglia globale da 0.25 gradi.

È utile quando vuoi una previsione globale rapida, basata su IA, con lo stesso schema API di GFS, GEFS e altri dataset. Non sostituisce automaticamente un modello fisico; spesso il valore sta nel confronto operativo.

Per struttura in quota usa AIGFS Pressure. Per scenari probabilistici usa AIGEFS Surface o AIGEFS Pressure.

APCP –Accumulated Precipitation (kg/m^2)
1 variant
NOAA GRIB2 Table 4.2-0-1

Accumulated precipitation represents the total water-equivalent amount of rain and snow during the output period. It is a primary field for hydrologic impacts and event totals.

  • Units: kg/m^2.
  • Use with the model time interval to interpret totals and compare to gauges.

PRMSL –Pressure Reduced to Mean Sea Level (Pa)
1 variant
NOAA GRIB2 Table 4.2-0-3

Pressure reduced to mean sea level is MSLP computed from surface pressure and temperature. It is used to locate highs and lows.

  • Units: Pa.

TMP –Temperature (K)
1 variant
NOAA GRIB2 Table 4.2-0-0

Air temperature is the thermal state of the atmosphere at the specified level. It influences density, stability, and energy exchange.

  • Units: K.

UGRD –U-Component of Wind (m/s)
1 variant
NOAA GRIB2 Table 4.2-0-2

U‑component of wind is the east‑west component of the horizontal wind. Combine with v for speed and direction.

  • Units: m/s.
  • Combine u and v components to compute speed and direction.
