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.
