This dataset provides daily WRF output for the Hawaiian Islands region for the following variables: daily rainfall (RAINNC), daily 2m temperature (TMEAN), max 2m temperature (TMAX), and min 2m temperature (TMIN) These quantities are provided for 20 WRF simulations over the time periods (1996-2005) and (2026-2035). Files are labeled based on the WRF simulation and year. (WRF 1-5 and 11-15: negative PDO phase, WRF 6-10 and 16-20: positive PDO phase). Data are also available from a federal repository upon request. Contact: casc@usgs.gov.
