The SWOT Science Simulator simulates projected SWOT altimetry observations that can be applied to an ocean general circulation model, allowing the exploration of ideas and methods to optimize information retrieval from the proposed SWOT Mission, which is currently baselined to launch in 2020.
From sea surface height (SSH) inputs, the software samples SWOT-like outputs on a swath along the orbit ground track, and adds noise signals. The noise signals represent instrument and geophysical errors, generated randomly following technical characteristics provided by the SWOT project team, and the knowledge of geophysical parameters. Not designed to directly simulate the anticipated payload instrument responses, this SWOT science simulator aims to provide statistically realistic outputs for the science community in an open-source and lightweight tool. The software is scalable and designed to support future refinements of orbital parameters, error budget estimations from the project team, and suggestions from the science community.
