GribStream

NOAA AI Global Ensemble Forecast System Pressure Levels (AIGEFS Pressure)

Codice GribStream: aigefspres

Descrizione

AIGEFS Pressure è l'ensemble IA NOAA/NCEP per struttura atmosferica in quota. Fornisce scenari su livelli di pressione standard invece di limitarsi ai campi superficiali.

Il dataset aigefspres è utile per capire come cambia l'incertezza in quota: profili termici, vento, altezza geopotenziale, umidità e moto verticale tra membri ensemble.

In GribStream puoi confrontarlo con GEFS, IFS ENS e AIFS Ensemble usando la stessa forma di richiesta.

Per i campi vicino alla superficie usa AIGEFS Surface. Per la versione deterministica su livelli di pressione usa AIGFS Pressure.

HGT –Geopotential Height (gpm)
13 variants
NOAA GRIB2 Table 4.2-0-3

Geopotential height is the altitude of a pressure surface in the atmosphere. It is the primary field for identifying ridges, troughs, and large‑scale flow patterns.

  • Units: gpm.

SPFH –Specific Humidity (kg/kg)
13 variants
NOAA GRIB2 Table 4.2-0-1

Specific humidity is the mass of water vapor per mass of air at the specified level. It is central to moisture transport.

  • Units: kg/kg.
  • Higher values indicate more atmospheric moisture and greater cloud or precip potential.
