Arctic System Reanalysis version 2

The Arctic System Reanalysis (ASR) is produced using a high-resolution version of the Polar Weather Research and Forecasting Model (PWRF) and High Resolution Land Data Assimilation (HRLDAS) systems that have been optimized for the Arctic. The final version of 15 km horizontal resolution data set which spans 2000-2016 is available on line through the NCAR's RDA. Similar to ASR version 1, ASR version 2 has 34 pressure levels (71 model levels), 31 surface (including 3 soil variables) and 11 upper air analysis variables, 71 surface (including 3 soil variables) and 17 upper air forecast 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.

ASR version 2 will be updated through 2019, then reran (2000-2019) using the most recent version of Polar WRF and WRFDA plus many other enhancements. This newer version, ASR version 2.5, should be available starting in mid-2020 and will be kept up-to-date through 2020 with a delay of about 3 months.
