The PSU/NCAR mesoscale model (known as MM5) is a limited-area, nonhydrostatic, terrain-following sigma-coordinate model designed to simulate or predict mesoscale atmospheric circulation. The model is supported by several pre- and post-processing progr...

Fortran 95 code for real-time weather forecasts.

Fortran 90 code for climate modelling.

Finds the total energy, charge density, and electronic structure of systems made of electrons and nuclei, using pseudopotentials and a plane-wave basis.

Code for climate modeling, radiation, and astrophysics.

Large collection of general purpose libraries and modules in Fortran and C developed at CERN, oriented towards the needs of a physics research laboratory: general mathematics, data analysis, and detector simulation.

Performs ab-initio quantum-mechanical molecular dynamics (MD) using pseudopotentials and a plane wave basis set. The approach implemented in VAMP/VASP is based on a finite-temperature local-density approximation (with the free energy as variational qu...

Used operationally by the U.S. Navy for short-term numerical weather prediction for various regions around the world. Parts of the code can be downloaded from the site, with registration.

Code for a neural network parametrization of deep-inelastic proton, deuteron and non-singlet structure functions.

Programs for electronic structure calculations within Density-Functional Theory and Density-Functional Perturbation Theory, using a Plane-Wave basis set and pseudopotentials. PWscf is released under the GNU General Public License.
