I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Hydrology Paper of the Day @ryanpad.bsky.social @wslresearch.bsky.social on improving hydrological forecasts by application of the Temporal Fusion Transformer ML model: wavelet transforms and emsemble forecasts; how to select seeds in the context of predictive skill; and application to Switzerland.
New study by Konrad and Ryan in my team @wslresearch.bsky.social as part of @extremeswsl.bsky.social
Some randmoness can help in sub seasonal streamflow and water temperature forecasts.

The dependence of Deep Learning models on randomness is often neglected, which can lead to problems in operational forecasting with extended forecast periods. I am pleased to share our new paper with potential solutions for using this randomness to improve forecast quality. rdcu.be/eX8Xg

Hydrology Paper of the Day @christost.bsky.social @georgiapapachar.bsky.social on consistent loss functions: explicit definitions and examples; how these loss functions are utilized to evaluate point predictions; loss functions and transformations; and applications to climatology and hydrology.
Happy (😊) to share our latest paper on variable transformations in consistent loss functions:

How many glaciers will exist by 2100 at +1.5 °C vs +4 °C warming? Our new study led by @landervt.bsky.social , projects the extinction year of ~200,000 glaciers worldwide. 🌍🧊
Can you imagine the Alps with only 20 glaciers remaining?
