John Brakebill
John Brakebill is the Deputy Director of the Water Mission Area (WMA) Integrated Modeling and Prediction Division.
John provides leadership and management skills for a diverse group of multi-disciplinary researchers, scientists, data analysists, and modelers responsible for developing, maintaining, and applying integrated, interdisciplinary water modeling predictions and forecasts using state-of-the-art enterprise approaches and systems. He previously served as an Associate Director in the Maryland-Delaware-DC Water Science Center where he spent the first 32 years of his career gaining experience in regional and national scale surface-water transport modeling (SPARROW), supervision and management, GIS analysis and applications, and geospatial data development. John also has served as a USGS mentor and is a facilitator for the USGS Leadership Intensive course.

CONUS404: The NCAR-USGS 4-km long-term regional hydroclimate reanalysis over the CONUS
A unique, high-resolution, hydroclimate reanalysis, 40-plus-year (October 1979–September 2021), 4 km (named as CONUS404), has been created using the Weather Research and Forecasting Model by dynamically downscaling of the fifth-generation European Centre for Medium-Range Weather Forecasts (ECMWF) atmospheric reanalysis of the global climate dataset (ERA5) over the conterminous United States.
