Rocketsonde buoy system : observing system simulation experiments

2009
The research presented here provides measurements of the negative impact of the Pacific and Arctic data voids on numerical weather predictability downstream over North America, and the extent to which the detrimental effects can be mitigated with rocket soundings from anchored buoys within the Rocketsonde Buoy System (RBS).

Observing-Systems Simulation Experiments: Past, Present, and Future

Bulletin of the American Meteorological Society, 1986
Abstract A summary of the history of observing-systems simulation experiments (OSSEs) is presented together with a description of current methodology, its capabilities and limitations, and considerations for the design of future experiments. These experiments are defined as a type of sensitivity study and are contrasted with real-data experiments ...

Observing System Simulation Experiments to Assess the Potential Impact of New Observing Systems on Hurricane Forecasting

Marine Technology Society Journal, 2015
AbstractObserving System Simulation Experiments (OSSEs) are an important tool for evaluating the potential impact of new or proposed observing systems, as well as for evaluating trade-offs in observing system design, and in developing and assessing improved methodology for assimilating new observations.

The Accuracy of Trajectory Models as Revealed by the Observing System Simulation Experiments

Monthly Weather Review, 1985
Abstract Fourteen observing system simulation experiments (OSSE) wore conducted using the results from a mesoscale model on the Oxidation and Scavenging Characteristics of April Rains(OSCAR) experiment to test the accuracy of trajectory models. Our results indicate that the current synoptic network and observational frequency over North America are ...

The Biodiversity Observing System Simulation Experiment (BOSSE) v1.

The Observing System Simulation Experiments are simulation tools that support the development, benchmarking, and evaluation of remote sensing missions and methods. The study of biodiversity, from remote sensing, and particularly that of plant diversity,  is an emerging topic with potentially beneficial outcomes for global-scale monitoring and ...

Global Observing System Simulation Experiments of the Ionosphere, Thermosphere and Plasmasphere

2013
Abstract : The overall goal of this project was to set up a simulation framework and testbed for ionosphere-thermosphere (IT) data assimilation that could be used to investigate: a) the impact of sensor systems upon the performance of data assimilation algorithms; b) the impact of improvements in data assimilative algorithms upon the performance of ...

Observing System Simulation Experiments (OSSEs) for Air Quality Applications

2016
In the past few years a growing amount of space observations focusing on atmospheric composition has become available and this trend will continue with the launch of new satellites (ESA-Sentinels, NASA-TEMPO and JAXA air quality and climate mission) in the near future. To justify the production and launch of these expensive instruments, there is a need

BOSSE: The Biodiversity Observing System Simulation Experiment for Remote Sensing

Climate change and human activities jeopardize ecosystems’ biodiversity, functions, and services. However, biodiversity monitoring is resource-intensive and unable to provide the coverage and resolution necessary to understand biodiversity responses to these drivers.
