The CLIMAAX project joined the 3th edition of the Climateurope2 webstival, which promoted insightful community discussions on the design, use, quality, business innovation, and policy drivers of climate services. This online conference took place on 19-20 September.

In a parallel session of Friday, from 9:30 to 10:15 CEST, Christopher Polster (ECMWF) and Martin Kubáň (Kajo Services) gave a brief overview of the CLIMAAX Handbook and demonstrated the use of one its workflows with the example of an assessment of urban heatwave risks.

Kubáň, the lead developer of the heatwave workflow, took the participants through the steps of the workflow and demonstrate its capabilities. Participants then had the opportunity to get hands-on and customize a part of the presented assessment to an urban area of their choice.

The hands-on session was based on Jupyter notebooks and could be run inside the browser with binder, a free cloud computing service, but experienced users were encouraged to set up a local computing environment beforehand (the instructions are available here).

About 1 GB of data was downloaded when following along with the workflow demonstration. Basic experience with the Python programming language was desirable but not a necessary requirement for participation.
