Home > WFS (WAM-IPE Forecast Model)

The coupled WAM-IPE model, developed in partnership between the Space Weather Prediction Center and the Environmental Modeling Center, provides a specification of ionosphere and thermosphere conditions with 4x/day forecasts two days out in response to solar, geomagnetic, and lower atmospheric forcing. The Whole Atmosphere Model (WAM) is an extension of the Global Forecast System (GFS) with a spectral hydrostatic dynamical core utilizing an enthalpy thermodynamic variable to 150 vertical levels at T62 resolution, with a model top of approximately 3 x 10-7 Pa. It also consists of a data assimilation system (WDAS). The Ionosphere Plasmasphere Electrodynamics (IPE) model provides the plasma component of the atmosphere. It is a time-dependent, global 3D model of the ionosphere and plasmasphere from 90 km to ~10,000 km at approximately a 2-degree resolution.
