Day 2: Climate Data -- Tuesday 11 August 2026 Probably 14:00-18:00 UTC
14:00-14:45 UTC - Keynote: The value of open data in environmental sciences: forecasting river flow with open tools alone
Thiago Nascimento (EAWAG)
This talk presents a streamlined workflow for generating a river streamflow forecast for a single catchment using only open data and openly available tools. The approach combines RivRetrieve for accessing river data, delineator for rapid catchment boundary delineation, and dynamical.org for cloud‑optimized weather and climate inputs. Using these datasets, an LSTM rainfall–runoff model is trained with NeuralHydrology and applied to the July 2023 southern Brazil flood, where the resulting streamflow forecast successfully reproduced the observed streamflow peak several days in advance. The talk concludes with a brief discussion of limitations, including reliance on a single weather source, a single‑basin LSTM, and uncertainty derived only from forecast forcing, and encourages attendees to explore the accompanying reproducible notebooks for hands‑on experimentation.
A live stream of the pre-recorded keynote will begin at 14:00 UTC, followed immediately by a live Question and Answer session with the speaker.
14:45-15:00 UTC - Break
15:00-17:00 UTC - Workshop: How to access petabytes of weather forecasts from your laptop
Jake Zwart (USGS and Alden Keefe Sampson (Dynamical)
Accessing large-scale meteorological forecasts is often slow and labor‑intensive, but new fast, interoperable tools are easing this burden. dynamical.org offers open, analysis-ready weather data updated nearly in real time, with a rapidly expanding catalog of global operational models. The platform enables applications such as hydrologic forecasting, algal bloom prediction, and NASA-supported snow‑cover estimation. Ongoing development will broaden support for major global models and emerging AI-based forecasts, helping users apply modern weather data more effectively. In this workshop, we will show participants how to access these data from their laptops.
A traditional part of AEMON-J meetings in the past has been to openly discuss ideas for new, joint projects.
This time in the schedule is to bring up such ideas, perhaps inspired by the workshops earlier that day, and discuss.
If no such ideas are pitched, this time can also be used for small talk, networking, and other social activities.
