Abstract:

U.S. National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) numerical weather prediction model 8-day, 3-hourly forecast for the globe at approximately 50-km or 0.5-deg resolution.

Purpose:

PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region.

Credit:

The Pacific Islands Ocean Observing System (PacIOOS) is funded through the National Oceanic and Atmospheric Administration (NOAA) as a Regional Association within the U.S. Integrated Ocean Observing System (IOOS). PacIOOS is coordinated by the University of Hawaii School of Ocean and Earth Science and Technology (SOEST).

Lineage:

Statement:

2011-06-02T00:00:00Z Subset 0.5-deg NCEP GFS daily from nomads server via OPeNDAP and Python.
2023-01-24T21:20:00Z Removed erroneous inclusion of "net" in the long_name and standard_name of the variables dlwrfsfc (surface_downwelling_longwave_flux) and dswrfsfc (surface_downwelling_shortwave_flux). Added variables ulwrfsfc (surface_upwelling_longwave_flux) and uswrfsfc (surface_upwelling_shortwave_flux) for users wishing to compute net downward fluxes (e.g., dlwrfsfc minus ulwrfsfc and dswrfsfc minus uswrfsfc).
