Ensemble Forecasts from EnKF Data Assimilation (GSI EnSRF, JEDI LETKF/LGETKF)

These grib2 files contain ensemble forecast data including hourly accumulated precipitation, hourly composite reflectivity, and hourly maximum 2-5km updraft helicity from Ensemble Kalman Filter data assimilation. These datasets were prepared for submission of GRL manuscript.
