9. Glossary¶
- CCPP
Model agnostic, vetted, collection of codes containing atmospheric physical parameterizations and suites for use in NWP along with a framework that connects the physics to host models
- chgres_cube
The preprocessing software used to create initial condition files to “coldstart” the forecast model. The initial conditions are created from either GFS GRIB2 or NEMSIO data.
- CIME
The Common Infrastructure for Modeling the Earth (CIME - pronounced “SEAM”) provides a Case Control System for configuring, compiling and executing Earth system models, data and stub model components, a driver and associated tools and libraries.
- FMS
The Flexible Modeling System (FMS) is a software framework for supporting the efficient development, construction, execution, and scientific interpretation of atmospheric, oceanic, and climate system models.
- FV3
The GFDL Finite-Volume Cubed-Sphere Dynamical Core (FV3) is a scalable and flexible dynamical core capable of both hydrostatic and non-hydrostatic atmospheric simulations.
- GRIB2
The second version of the World Meterological Organization’s (WMO) standard for distributing gridded data.
- NCEP
National Centers for Environmental Prediction, an arm of the National Weather Service.
- NCEPLIBS
The NCEP library source code and utilities required for chgres_cube, the UFS Weather Model, and UPP.
- NCEPLIBS-external
A collection of third-party libraries required to build NCEPLIBS, chgres_cube, the UFS Weather Model, and UPP.
- NCL
An interpreted language designed specifically for scientific data analysis and visualization. More information can be found at https://www.ncl.ucar.edu.
- NEMS
The NOAA Environmental Modeling System - a software infrastructure that supports NCEP/EMC’s forecast products.
- NEMSIO
A binary format for atmospheric model output on the native gaussian grid.
- NetCDF
A set of software libraries and machine-independent data formats that supports the creation, access, and sharing of array-oriented scientific data.
- Stochastic physics
A package of stochastic schemes used to represent model uncertainty: SKEB (Stochastic Kinetic Energy Backscatter), SPPT (Stochastically Perturbed Physics Tendencies), and SHUM (Specific Humidity)
- Suite
A collection of primary physics schemes and interstitial schemes that are known to work well together
- UFS
A Unified Forecast System (UFS) is a community-based, coupled comprehensive Earth system modeling system. The UFS numerical applications span local to global domains and predictive time scales from sub-hourly analyses to seasonal predictions. It is designed to support the Weather Enterprise and to be the source system for NOAA’s operational numerical weather prediction applications
- UPP
The Unified Post Processing System, developed at NCEP and used operationally for models maintained by NCEP. The UPP has the capability to post-process output from a variety of NWP models, including FV3.
- Weather Model
A prognostic model that can be used for short- and medium-range research and operational forecasts. It can be an atmosphere-only model or be an atmospheric model coupled with one or more additional components, such as a wave or ocean model.
