2012 Spring Experiment NWP Models and Guidance

The table below lists NWP models and guidance that will be available for testing and evaluation during the 2012 Spring Experiment. Additional details about the configuration of the guidance (e.g. specifics of parameterization schemes, setup of vertical grid, etc.) can be found in the 2012 Spring Experiment Operations Plan.
