Global Ensemble Forecast System (Atmos Mean GEFS)

Description

GribStream Code: gefsatmosmean
Description: A component of the GEFS that provides average atmospheric conditions derived from ensemble forecasts, enhancing predictability and reducing uncertainty.
Product page: https://www.ncei.noaa.gov/products/weather-climate-models/global-forecast/
Key Features:
- Aggregates the outcomes of multiple ensemble members to produce a mean forecast, smoothing out extreme variations and providing a more stable prediction.
- Facilitates improved decision-making in weather-sensitive sectors by offering a balanced view of expected atmospheric conditions.
- Incorporates extensive meteorological data from global measurement networks and satellites.
Resolution: 0.25° global grid.
Temporal Coverage: Updated four times daily, with forecasts extending up to 16 days.
Primary Use Cases: General weather forecasting, agricultural planning, emergency management, and public safety.
