MM5 Programs

Below is a list of available MM5 programs.
View the schematic diagram to see the order of the programs and the flow of the data.

• Program TERRAIN - domain configuration, create terrestrial fields
• Program REGRID - create first-guess meteorological fields on MM5 grid
• Program LITTLE_R  - objective analysis (add observations to the first-guess)
  • Program RAWINS - objective analysis (older alternative to LITTLE_R)
• Program INTERPF - interpolate pressure level data to model coordinate
• Program MM5 - the dynamic model that performs the time integration
• Program NESTDOWN - create one-way nest or nested model input
• Program INTERPB - interpolate model sigma-level data to pressure levels
• Program RIP - plot utility
• Program GRAPH - plot utility
• Program MM5toGrADS - plot utility

Once you are able to run all these programs successfully, we hope that you'll have some confidence in handling the MM5 modeling system programs when you start your cases.
Good Luck!
