Reduced order modeling techniques play an important role in many areas of science and engineering and are an emerging topic in geophysical simulations nowadays. We present pyROM, a comprehensive, user-friendly, and open-source computational framework for model order reduction in geophysical problems. Users have free access to the framework and can apply model order reduction methods to reproduce the dynamic response of the high-dimensional models with good accuracy while achieving significant computational savings. pyROM contains implementations of several efficient model reduction methods and is written in a clear and concise way targeting a wide range of users, including those with little or no knowledge of model reduction principles.
