 Before we start, I would like to give a brief introduction about today's clinic. The goal of the clinic is to encourage the community to create their own model and data components under the PMT modeling framework. We also want to encourage people to share the Jupyter notebooks for their components or their modeling workflows using the CSDMS and HydroShare capability to support the reproducible research. In today's clinic, we will first have Eric, who is the senior software engineer from the CSDMS team, to talk about the basic model interface and the PMT modeling framework. We are also very glad that we invited Rich McDonald, who is the hydrologist from the USGS, to talk about his work for the PRMS model components. Followed by that, I will introduce the CSDMS and HydroShare capability and a data component. Then you guys will have the hands-on exercise using the HydroShare and Acquacity Jupyter Hub.
