The data are based on 27km resolution simulations using the Weather Research and Forecasting (WRF) model, covering the period 1981-2017. The domain includes CONUS and the North Pacific basin. Each year includes at least a 5-member ensemble, with up to a 25-member ensemble for selected wet/dry years.
The Calibrated and Systematic Characterization, Attribution, and Detection of Extremes (CASCADE) project advances the Nation’s ability to identify and project climate extremes and how they are impacted by environmental drivers.
