Study the Earth and skies 
with our community-powered software

NSF NCAR partners with the community to create software made specially for Earth system science. This gives researchers a platform to expand their understanding of the Earth, skies, weather, sun, clouds, atmosphere. Scientists get a place to stand to move the world. 

NSF NCAR software packages are freely available—and free of charge—thanks to NSF NCAR’s longtime commitment to the computing and scientific community.
