For this reason a stopping point must be established. Each model has its own data cutoff and schedule. Scheduling refers to how often a model is run. This allows them to update and include new observations. The more recent the meteorological data is, the more precise the model is able to depict the current weather situation.
Data cutoffs and scheduling are integral parts of a model's input and output.
The data cutoff stops the input of current information. The schedule denotes the time when the model uses the data to make its runs. This model provides forecasts over the United States at a very high resolution from 03Z and 18Z out to 33 hours. The ETA model also provides a regional forecast over the United States soon after the 0Z, 3Z, 12Z, and 18Z synoptic times for early guidance out to 48 hours. The National Weather Service and meteorological community are able to access and use this model.
