Description Data Cutoffs and Scheduling Description Models use atmosphereic observations to analyze and predict the future state of the atmosphere.
Most models use information from other models to initilize the data.
Althought these models have many things in common, they differ in purpose and content. One thing that all models have in common is the establishment of analyses and initial conditions that models use to describe the current state of the atmosphere. Also, all models strive to forecast the future state, and all models disseminate the analyses and present a useful forecast to a wide variety of users. Models are unable to continously take in new data. For this reason a stopping point must be established.
