River pollution threatens Des Moines, Iowa's drinking water
Local officials are warning more than half a million Iowans in the state's capital city and suburbs that near-record level of pollutants in its rivers could make drinking water dangerous if immediate steps are not taken to reduce demand. But the officials are declining to explain what they believe has caused the surge in nitrate levels, which has historically been tied to runoff from farmland draining into Des Moines-area rivers. The water utility is issuing a first-ever ban on lawn watering fo…

I remember BIll Stowe clashing with ag-lobbyists, where the lobbyists claimed they were doing exactly the right things to protect water in Iowa, and that further legislation and lawsuits were not necessary.
Now, in 2025, Central Iowans must curtail water usage, not because there isn't enough water, but because the source water is too contaminated with farm runoff nitrates.

this was where it all started

Weather tracker: Storms make way for summer heat in Europe https://www.theguardian.com/environment/2025/jun/09/weather-tracker-storms-summer-heat-europe-south-africa

I'm interested in making my own visualizations of weather radar data to display patterns in a region of the US (covered by multiple stations) over longish periods of time (e.g., a month).
Think something like this year of US radar, but smaller & shorter in my case: https://www.youtube.com/watch?v=FPuDPxK88g0
I'm familiar with mapping and animation in Python/R, but not weather radar data. I've been looking for tutorials, but haven't been able to track any down yet. Pointers very much welcome

LaDCast: A Latent Diffusion Model for Medium-Range Ensemble Weather Forecasting
Accurate probabilistic weather forecasting demands both high accuracy and efficient uncertainty quantification, challenges that overburden both ensemble numerical weather prediction (NWP) and recent machine-learning methods. We introduce LaDCast, the first global latent-diffusion framework for medium-range ensemble forecasting, which generates hourly ensemble forecasts entirely in a learned latent space. An autoencoder compresses high-dimensional ERA5 reanalysis fields into a compact representa…
