Decision makers are demanding more timely and reliable environmental predictions and information days to months in the future. Weather events that have significant consequences for society and the economy are of particular interest. It is incumbent on the weather and climate community to accelerate improvements to the building blocks that advance understanding and improve forecasts of these events, including observational networks, data assimilation systems and statistical/dynamical models. Emphasis is placed on the extent to which the ocean observing system is meeting the needs of the weather and climate community to develop and deliver improved data, products and knowledge required by decision makers. This Town Hall will discuss the ability of the current observing systems, data, and information needed to meet requirements for weather research and services; identify data gaps in observing capabilities; and approaches to integrated system of global ocean observations for addressing these new challenges.
