Prediction of Earth's Effective Angular Momentum Functions

Prediction of effective angular momemntum functions of atmosphere, ocean, hydrology, and sea-level

In this project, we provide the predictions of Effective Angular Momentum Functions of the Earth (EAM) with a forecasting horizon of two weeks. The predicted EAM include

  1. Atmospheric Angular Momentum (AAM)
  2. Oceanic Angular Momentum (OAM)
  3. Hydrological Angular Momentum (HAM)
  4. Sea-Level Angular Momentum (SLAM)

The methodologies, descriptions, and predictions are provided operationally on ETH Zürich Geodetic Prediction Center.

An example of the prediction accuracy of AAM, in terms of mean absolute error.
