COMME N 1) what is the ultimate purpose of the user of the Reforecasts: An Important reforecasts (e.g., diagnosing operational model behavior, studying predictability, making opera- Dataset for Improving tional forecasts), and 2) can the stripped-down model furnish results Weather Predictions competitive with an operational model? — B O B GLAHN Only by running a series of tests could the answer to Meteorological Development Laboratory, 2) be determined, and even then it would only apply to Office of Science and Technology, NOAA/National Weather Service, the specific situation. It is possible that a long sample of Silver Spring, Maryland low-resolution reforecasts would be more appropriate than a shorter sample of operational model forecasts for short-range forecasting than for longer range, or vice versa. For instance, the reforecast model will undoubtedly give good forecasts for the first day or amill et al.
