ICESEE

ICESEE (ICE ShEet state and parameter Estimator) is a data assimilation software framework designed for coupling with ice sheet models such as ISSM, Icepack, and idealized models like Lorenz-96. It provides a modular, extensible platform for applying ensemble-based data assimilation techniques in glaciological modeling and beyond.

What is ICESEE?

ICESEE simplifies the implementation of advanced data assimilation workflows—such as the Ensemble Kalman Filter (EnKF) and its variants—across a range of geophysical models. It is designed with:

• A modular Python interface
• Seamless integration with external model codes (MATLAB, Firedrake, ISSM, etc.)
• Support for high-performance computing and containerized workflows
• Scalability for future integration with cloud platforms like AWS and portals like GHUB
