The simulation of observations—a critical Community Global Observing System Simulation Experiment (OSSE) Package (CGOP) component—is validated first by a comparison of error-free simulated observations for the first 24 h at the start of the nature run (NR) to the real observations for those sensors that operated during that period. Sample result...Institution National Oceanic and Atmospheric Administration - NOAA
Experiments with a global Observing System Simulation Experiment (OSSE) system based on the recent 7-km resolution NASA nature run known as the G5NR were conducted to determine the potential value of proposed Global Navigation Satellite System (GNSS) radio occultation (RO) constellations in current operational numerical weather prediction system...Institution National Oceanic and Atmospheric Administration - NOAA
The mainstay of the global radio occultation (RO) system, the COSMIC constellation of six satellites launched in April 2006, is already past the end of its nominal lifetime and the number of soundings is rapidly declining because the constellation is degrading. For about the last decade, COSMIC profiles have been collected and their retrievals a...Institution National Oceanic and Atmospheric Administration - NOAA
A modular extensible framework for conducting observing system simulation experiments (OSSEs) has been developed with the goals of 1) supporting decision-makers with quantitative assessments of proposed observing systems investments, 2) supporting readiness for new sensors, 3) enhancing collaboration across the community by making the most up-to...Institution National Oceanic and Atmospheric Administration - NOAA
