Abstract: NOAA scientists recently completed the generation of a ~30 year, daily medium-range global ensemble reforecast data set that uses roughly the same NCEP Global Ensemble Forecast System that was made operational in 2012. We maintain a hard-disk archive of 99 different output fields at the NOAA Earth System Research Lab in Boulder, which are readily accessible via web interface or ftp. An archive of the full model state is also available from US Department of Energy computers. In this webinar I will provide more information on the data set, will demonstrate several uses of reforecasts, including the statistical post-processing of precipitation forecasts, and will describe how to access the data.
