What is NSF Unidata?

U.S. National Science Foundation Unidata is a diverse community of education and research institutions with the common goal of sharing geoscience data and the tools to access and visualize that data. For more than 35 years, NSF Unidata has been providing data, software tools, and support to enhance Earth-system education and research. Funded primarily by the U.S. National Science Foundation, NSF Unidata is one of the University Corporation for Atmospheric Research (UCAR)'s Community Programs (UCP).

NSF Unidata's GitHub repositories contain code for software projects created or maintained by developers at the NSF Unidata Program Center. We actively encourage contributions to these projects in the form of issues and pull requests.
