1. Forecast Model Run Collections and ISO Ted Habermann There has been considerable discussion of describing multiple times in forecast datasets This is not the only challenge: 1.Dimensions 2.Shapes 3.Variables

2. University of Maine Circulation Model RunTime ForecastTime Variables

3. Dimensions 5 dimensions in a single dataset can be combined in any way to describe the shapes of variables
