Abstract

Satellite observations are a critical component of the global atmospheric observing system, and contribute substantially to the current accuracy of numerical weather forecasts. In this paper, two types of experiments related to the effectiveness of these and other observations are described. These are: Observing System Experiments (OSEs), which are conducted to evaluate the impact of an existing observing system; and Observing System Simulation Experiments (OSSEs) which are conducted to evaluate the potential for future observing systems to improve NWP, as well as to evaluate trade-offs in observing system design, and to develop and test improved methods for data assimilation. This paper summarizes the methodology for such experiments and presents selected results from OSEs to evaluate satellite data sets that have recently become available to the global observing system, such as AIRS and SeaWinds, and results from recent OSSEs to determine the potential impact of space-based lidar winds.
