Data and Products of the Global Deterministic Prediction System

The Global Deterministic Prediction System (GDPS) performs physical calculations to produce deterministic forecasts of atmospheric elements from the present day to 10 days in the future. Elements of the atmosphere include temperature, precipitation, cloud cover, wind speed and direction, and humidity. This product contains the raw numerical results of these calculations. The geographical coverage is global. The horizontal spatial resolution of the data is 15 km. Data is available for 33 vertical levels. The forecasts are carried out twice a day.
