Future Observing System Simulation Experiments

by Ross N. Hoffman and Robert Atlas

The Observing System Simulation Experiment or OSSE checklist presented here is meant to be a detailed guide to OSSE practitioners and OSSE consumers to evaluate the design of an OSSE system and OSSE experiments. It provides a step-by-step process to encourage the user to consider all aspects of good OSSE design principles. The current version of the OSSE checklist is directly applicable to weather-related observing, modeling and data assimilation (DA) systems. But very similar issues and concerns apply to OSSEs that would be used across a diverse range of geophysical domains and the user of the OSSE checklist should be able to translate the discussion presented here to these domains fairly directly.

The OSSE checklist based on a recent AMS publication titled "Future Observing System Simulation Experiments."

Your Experiment

This section is intended to record some minimal basic information about your OSSE.
Answers here provide context for the questions that follow.

  • What new instrument(s) and/or new technique(s) are you investigating?
  • What phenomena are of interest for the new instrument(s) and/or new technique(s)?
  • Describe your nature run (NR):
  • Describe your forecast and data assimilation (DA) systems:
  • Describe your experimental design (including your validation approach):
