Arctic System Reanalysis (ASR) Project

The Arctic System Reanalysis (ASR) is produced using a high-resolution version of the Polar Weather Forecast Model (PWRF) and High Resolution Land Data Assimilation (HRLDAS) systems that have been optimized for the Arctic. The final version of 30 km horizontal resolution data set which spans 2000-2012 is released in September 2014 and available on line through the NCAR's RDA. The interim version, released in May 2012, is also available for a limited period of time.The final version has 29 pressure levels, 27 surface and 10 upper air analysis variables, 74 surface and 16 upper air forecast variables, and 3 soil variables. Both the u- and v- winds relative to grid and relative to earth are present in the final version. The wind speed is also added.

NOTE: This dataset has been superseded by the Arctic System Reanalysis version 2, which is available in RDA dataset ds631.1.  Users are advised to access this newer dataset version.
