  abstract = {We review the assessment of existing observations with Observing System Experiments (OSEs) and the Forecast Sensitivity to Observation Impact (FSOI) approach. Although care is needed when interpreting their results, the information they provide is largely consistent. The Ensemble of Data Assimilations (EDA) provides an affordable and manageable framework for simulating the impact of future observing systems. Recent experience comparing EDA predictions with the subsequent impact of real measurements gives us some confidence that, with appropriate interpretation and care, they provide useful information that can help guide the future evolution of the global observing system.},
