A new CAM6 + DART reanalysis with surface forcing from CAM6 to other CESM models

Abstract An ensemble Kalman filter reanalysis has been archived in the Research Data Archive at the National Center for Atmospheric Research. It used a CAM6 configuration of the Community Earth System Model (CESM), several million observations per day, and the Data Assimilation Research Testbed (DAR...
