GSI 3D HYBRID FOR ARW USING GLOBAL ENSEMBLE FORECAST
Introduction
This exercise runs the GSI 3 Dimensional Ensemble-Variational (EnVar) hybrid analysis with the ARW background, conventional data at 12z August 12, 2018.
Please note the ARW background field is provided in netcdf format, and the NAM BE is employed as the background error covariance in this experiment. The global ensemble forecasts are linked to run this GSI hybrid test.
