This historical dataset is recommended for ancillary use only and not as a primary research dataset. It has likely been superseded by a newer, improved dataset.
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NOTE: This dataset has been superseded by the Arctic System Reanalysis version 2, which is available in RDA dataset ds631.1.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.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
