This dataset includes the WRF-simulated daily hydroclimate data over the US Puget Sound region during 1981-2020. The data includes the following single-level variables at 6-km grid spacing: precipitation (PREC_ACC_NC), 2-meter temperature (T2), snow water equivalent (SNOW), wind divergence (WindDiv), integrated water vapor (IWV), integrated vapor transport (uvIVT). The WRF model configuration and model validation can be found in Chen et al. (2018) and Chen et al. (2019). The scripts used to analyze these hydroclimate conditions as in Chen et al. (submitted) will be included in this repo after the manuscript is published. Reference: Chen, X., L. R. Ruby, N. Sun, Impact of ENSO and MJO on the U.S. Puget Sound Regional Hydroclimate.
