Atmospheric River Workshop
Event Location: Virtual
April 22-23, 2025
11AM – 5PM EDT
This invite-only, virtual event is a two-day Atmospheric River (AR) workshop that will include presentations from the Earth Prediction Innovation Center (EPIC), Global Systems Laboratory (GSL), Physical Sciences Laboratory (PSL), Weather Program Office (WPO), Environmental Modeling Center (EMC), Weather Prediction Center (WPC), National Weather Service (NWS), Center for Western Weather and Water Extremes (CW3E), Cooperative Institute for Research to Operations in Hydrology (CIROH) and others to highlight recent advances and future work in AR science, modeling, forecasting, impacts and more. The workshop will also include running applications such as GraphCast, FourCastNetv2, and PanguWeather for an AR event impacting the United States west coast.
