Observing System Simulation Experiment to Reproduce Kelvin Wave in the Venus Atmosphere

Atmosphere, 2020
Planetary-scale 4-day Kelvin-type waves at the cloud top of the Venus atmosphere have been reported from the 1980s, and their significance for atmospheric dynamics has been pointed out.

Future Observing System Simulation Experiments

Bulletin of the American Meteorological Society, 2016
Abstract As operational forecast and data assimilation (DA) systems evolve, observing system simulation experiment (OSSE) systems must evolve in parallel. Expected development of operational systems—especially the use of data that are currently not used or are just beginning to be used, such as all-sky and surface-affected microwave ...

Observation system simulation experiments for a global wind observing sounder [PDF]

Geophysical Research Letters, 2012
Observing System Simulation Experiments (OSSEs) are a powerful tool used to assess the potential impact on numerical weather prediction skill of planned or hypothetical future observing systems. Over the past several years an international Joint OSSE collaboration has emerged centered on the use of NASA's and NOAA's data assimilation systems.

Use of Observing System Simulation Experiments in the United States [PDF]

Bulletin of the American Meteorological Society, 2020
AbstractThe NOAA Science Advisory Board appointed a task force to prepare a white paper on the use of observing system simulation experiments (OSSEs). Considering the importance and timeliness of this topic and based on this white paper, here we briefly review the use of OSSEs in the United States, discuss their values and limitations, and develop five
