Observing System Simulation Experiment: Development of the system and preliminary results

Journal of Geophysical Research, 2011
[1] An Observing System Simulation Experiment (OSSE) was developed and conducted to assess the potential impact of different observing strategies of field experiments on analysis and short-term forecasts. A Mei-Yu front rainfall case study, occurring in 2003 in southeastern Asia, was utilized to demonstrate the OSSE application to field experiments ...

Monitoring the Northern Current in the Gulf of Lions with an observing system simulation experiment

Scientia Marina, 2012
The coastal circulation in the Gulf of Lions (GoL) is influenced by the Northern Current (NC), forced by a complex wind system and also affected by important river discharges from the Rhône River.

Robustness of Observing System Simulation Experiments

Tellus A: Dynamic Meteorology and Oceanography, 2023
Observing System Simulation Experiments (OSSEs) are used to investigate the potential performance of proposed new instruments on numerical weather prediction (NWP). As OSSEs involve a framework in which the atmosphere and observations are all completely simulated, it is necessary to perform validation of the OSSE to ensure that it is sufficiently ...

Exploring the potential of thermal infrared remote sensing to improve a snowpack model through an observing system simulation experiment [PDF]

The Cryosphere, 2023
The assimilation of data from Earth observation satellites into numerical models is considered to be the path forward to estimate snow cover distribution in mountain catchments, providing accurate information on the mountainous snow water equivalent (SWE)
