The decade long (2000-2010) Arctic System Reanalysis (ASR) project is nearing completion. The ASR, which can be viewed as a blend of modeling and observations, will provide ultimately a high resolution description in space (10-km) and time (3-hr) of the atmosphere-sea ice-land surface system of the Arctic. The ASR will permit reconstructions of the Arctic system's state, thereby serving as a state-of-the-art synthesis tool for assessing Arctic climate variability and monitoring Arctic change. The ASR will ingest and generate a large volume of data, all of which we consider to be a community resource. The Polar Meteorology Group will run the ASR on the Ohio Supercomputer Center's (OSC) systems, process output and maintain the secure archive of all reanalysis data at OSC. The final ASR results will be available for download from the NCAR DSS server and NOAA ESRL will provide online analyses of ASR fields. The first generation ASR (ASR-Interim) has been produced and spans the years 2000-2009 at 30-km resolution. From evaluations of the earlier ASR-prototype results, the community recognized that ASR can produce long time series at high resolution of temporally and dynamically consistent atmospheric and surface fields for Arctic studies. Here, we present some aspects and results from the ASR-Interim. We strongly encourage feedback and suggestions from research community for the ASR 10-km final run.
