Hello, I am Richard Grumm, the Scientific Operations Officer at the National Weather Service Office in State College. I have been in State College since 1993 and in the NWS since 1987. I began using NCEP ensembles in 1999 and have been trained and have been training others on using ensembles since about 2000. I hope you enjoy this module, and find it useful in your work as an operational forecaster.
