GribStream

GEFS Aerosol and Chemistry Fields

Código GribStream: gefschem

Descrição

GEFS Chem expõe campos de aerossóis e composição atmosférica associados ao sistema GEFS da NOAA.

Essas variáveis são úteis quando o produto depende não apenas do tempo meteorológico, mas também de fumaça, poeira, aerossóis e condições de visibilidade ou radiação.

No GribStream, gefschem permite consultar esses campos por coordenada e lead time, usando os seletores técnicos do catálogo como fonte de verdade.

Combine com GFS, GEFS Atmos ou UVI quando o caso de uso envolve exposição ambiental ou energia solar.

AOTK –Aerosol Optical Thickness (dimensionless)
6 variants
NOAA GRIB2 Table 4.2-0-3

Aerosol optical thickness represents the column-integrated attenuation of solar radiation by aerosols. Larger values indicate hazier conditions and reduced surface sunlight.

  • Units: dimensionless.
  • Useful for visibility, air quality, and solar energy assessments.

COLMD –Column-Integrated Mass Density (kg/m^2)
6 variants
NOAA GRIB2 Table 4.2-0-20

Column-integrated mass density is the total mass per unit area through the vertical column for the specified species. It summarizes column burden and is useful for transport diagnostics.

  • Units: kg/m^2.
