NCAR partners with the community to create software specially designed to support Earth system science. This gives scientists the platform they need to expand our understanding of the Earth, the skies, the weather, the wind, the clouds.… and to change the world. NCAR software packages are freely available—and free of charge—thanks to NCAR’s longtime commitment to the computing and scientific community.

DART is the Data Assimilation Research Testbed. Its data assimilation capabilities provide a bridge between real-world data and a wide range of computational models, with a rigorous framework.

NCAR’s classic math libraries are a geophysics mainstay that includes the Fortran libraries FFTPACK, FISHPACK, MUDPACK, and SPHEREPACK.

These libraries, developed at NCAR from 1970 to 1990, are still in use thanks to the value they bring to the scientific community.
