This effort is aimed at developing an Arctic System Reanalysis (ASR). The ASR will provide a high resolution description in space and time of the atmosphere-sea ice-land surface-river system of the Arctic.

This effort focuses on development of an Arctic System Reanalysis (ASR). The ASR, which can be viewed as a marriage between modeling and observations, will provide a high resolution description in space (20 km) and time (3 h) of the atmosphere-sea ice-land surface-river system of the Arctic. It will ingest historical data streams along with measurements of the physical components of the Arctic Observing Network being developed as part of the IPY. Gridded fields from the ASR, such as temperature, radiation and winds, will also serve as drivers for coupled ice-ocean, land surface and other models, and will offer a focal point for coordinated model inter-comparison efforts. The ASR will permit reconstructions of the Arctic system’s state, thereby serving as a state-or-the-art synthesis tool for assessing Arctic climate variability and monitoring Arctic change.
