Global Ensemble Forecast System (Chem GEFS)

Description

GribStream Code: gefschem
Description: A component of the GEFS that provides probabilistic forecasts of atmospheric chemical compositions globally.
Product page: https://www.ncei.noaa.gov/products/weather-climate-models/global-forecast/
Key Features:
- Utilizes ensemble forecasting to predict atmospheric chemical distributions.
- Enhances the ability to forecast air quality and chemical dispersal.
- Integrates data from satellite, ground-based observations, and chemical sensors.
Resolution: 0.25° global grid.
Temporal Coverage: Updated four times daily, with forecasts extending up to 5 days.
Primary Use Cases: Air quality forecasting, environmental monitoring, and research on atmospheric chemistry.
