The University of Wisconsin-Milwaukee Atmospheric Science Program used a Unidata Community Equipment Awards grant to deploy a server that hosts, among other things, a local The Littlest JupyterHub instance. Since its deployment in August 2021, the server, data received through Unidata's IDD network, and the local JupyterHub instance have supported student training and development in four Atmospheric Science courses and through UW-Milwaukee's Innovative Weather student traineeship program.

2023 Unidata Users Workshop

Unidata Users Workshop attendees

The Unidata Users Committee invites you to join Unidata staff, community members, and distinguished speakers this June in Boulder, Colorado. The goal of this year's workshop is to raise awareness about how to access and use Earth Systems Science data, and to explore approaches to tell the stories of our science in a way that is reproducible, responsible, and robust. Scientists and educators from the Earth Systems Science community will present ideas and techniques for making effective use of geoscience data and share activities, course materials, and ideas for improving education and research.

The Workshop is being held June 5-8 in Boulder, CO and online.

Version 1.5.0 of MetPy, a collection of tools in Python for reading, visualizing, and performing calculations with weather data, has been released. The project aims to mesh well with the rest of the scientific Python ecosystem, including the Numpy, Scipy, and Matplotlib projects, adding functionality specific to meteorology. This release brings a few new features, including the ability to plot fronts and boundaries with appropriate styling as well as parsing WPC surface bulletins.

AWIPS Tips: Visualizing Upper Air Soundings
