The U.S. National Center for Atmospheric Research (NCAR) has recently announced an important change that will impact users of the Earth Sciences data analysis and visualization package, the NCAR Command Language (NCL). Based on numerous factors NCAR has decided to transition away from future NCL development and instead focus efforts on providing Open Source tools in the Python ecosystem. Detailed plans about this transition are available from the NCL web site: www.ncar.ucar.edu. This splinter session will present the latest information on the future of NCL and NCAR's "Pivot to Python". We will address what this change means for current and future users of NCAR's open source tools. We invite discussion and feedback from the community, and will discuss how the community can get involved with this exciting change!
