North American Regional Reanalysis (NARR) for Arctic Research
NARR and PSD: The Arctic Research Office (ARO) has provided support to distribute the NARR data in direct access netCDF format and to develop of visualization and analysis tools. The goal is to provide the Arctic research community and other users of Arctic climate information with access to climate variability and change data on the smaller spatial scales that are needed for improved fundamental understanding and for decision support applications and assessment research.
Use these pages to plot the data or to composite different days or seasons together. The user can change the map and plotting options and can plot the data at different resolutions (1x1 or 1/3x1/3 degrees).

The NARR dataset is an extension of the NCEP Global Reanalysis which is run over the North American Region. The NARR model uses the very high resolution NCEP Eta Model (32km/45 layer) together with the Regional Data Assimilation System (RDAS) which, significantly, assimilates precipitation along with other variables. More information can be found at the NARR dataset information page.
Dataset was originally produced at NOAA's National Center for Atmospheric Prediction (NCEP) and is available in it's original grib format through NOAA NCDC's access page and from NCAR. More information is at NCEP's NARR web page.
