Quantitative Observing System Assessment Program (QOSAP)




AOML houses NOAA's Quantitative Observing System Assessment Program (QOSAP), which provides quantitative and objective assessment capabilities to analyze and evaluate current and future earth observation systems. These capabilities include observing system experiments (OSEs), which focus on identifying the impact of a current observing system on data assimilation and numerical weather prediction while testing ways to improve the quality and usefulness of data products.


The program also includes observing system simulation experiments (OSSEs) which focus on assessing the potential impact of proposed and future observing systems on numerical weather, ocean, and climate prediction.


By leveraging both OSEs and OSSEs, QOSAP aims to inform major decisions on the design and implementation of optimal observing systems as well as increase NOAA’s capacity to conduct quantitative observing system assessments.


AOML scientists created a step-by-step process to encourage consideration of aspects of good OSSE design principles. The resulting OSSE checklist, based on a recent AMS publication titled "Future Observing System Simulation Experiments", is available online here.
