Use of Observing System Simulation Experiments in the United …
2020年9月2日 · Under QOSAP, a state-of-the-art global OSSE system, an advanced hurricane OSSE system, and an internationally recognized first of its kind rigorous ocean OSSE system were developed. For global NWP, an OSSE system was developed for observation impact assessments based on the 7 km NASA Global Earth Observing System, version 5, nature run.
OSSEs - NASA
2022年5月25日 · We can estimate the impacts of proposed designs of new satellites using a type of study called an Observing System Simulation Experiment (OSSE). An OSSE uses computer models to test different designs of the new satellite systems before their instruments are actually built or deployed, and to compare the performance of the new satellites against ...
OSSEs on the FY-4M Geostationary Microwave Satellite ... - IEEE …
In this article, an OSSE based on the China Fengyun-4M (FY-4M) GEO microwave satellite is introduced in detail. The nature run (NR) of the OSSE is generated by the Mesoscale Weather Numerical Forecast System of the China Meteorological Administration (CMA-MESO), while the Global Forecast System of the CMA (CMA-GFS) is used to achieve the 4-D ...
【AI知识点】近似最近邻搜索(ANN, Approximate Nearest …
2024年10月17日 · 最近邻搜索(Nearest Neighbor Search, NNS) 是指在一个数据集中,给定一个查询点,找到与该点最接近的一个或多个点。 对于低维数据,如二维或三维空间,可以通过简单的几何方法(如 欧几里得距离 )快速完成这种搜索。
观测系统模拟和评估:进展及展望
观测系统模拟试验(Observing System Simulation Experiments,OSSEs)是一种敏感性试验,旨在回答新的观测系统或是对旧观测系统的重新部署带来的影响和价值的问题,通常指在数值天气预报和气候预测中的影响。 OSSEs还为在数值天气预报中应用新的数据类型以及优化已有数据类型提供支撑。 数值天气预报模式和卫星资料同化系统的快速发展(例如全天侯、全地表覆盖资料的同化等)以及未来大量的新型观测系统的部署(例如静止卫星上的红外高光谱及微波大气探测仪 …
