Caravan News🐪🐫
I just published Version 1.6. The main update is that the source data for CAMELS-AUS was upgraded to CAMELS-AUS v2. This means more basins (561 vs 222) and more recent streamflow data (2022 vs 2014).

🔍 Why GRIT is a game-changer:
📏 Delivers 30m resolution across 19 million km of rivers and streams
🤖 Enables automatic updates using new satellite imagery and elevation data
🧭 Supports vector-based, global-scale river analysis
🧠 Powers AI/ML modeling in hydrology and environmental science
🌎 Unlike existing datasets that simplify rivers into single-threaded, convergent flows based on elevation, GRIT captures both converging and diverging flow patterns — a crucial advance for understanding river systems, especially in flood-prone, densely populated areas.
We’re thrilled to share GRIT, the world’s first high-resolution global river network that maps how rivers both merge and split across the landscape — now published in Water Resources Research (Wortmann et al., 2025).

1/ How to Stop Being Surprised by Unprecedented Weather
Our new @naturecomms.bsky.social paper provides our multi-author perspective on methods to anticipate extreme weather and reduce impacts, shifting from reacting with surprise towards resilience.

I'm back to Bluesky.. going to give it another go!
The last few months have been busy..
Many congratulations to Bailey Anderson on a successful PhD defence! Sincere thanks to external examiner Ross Woods, internal Linda Speight, & co-supervisor @simondadson.bsky.social. Bailey's thesis focused on large-sample approaches to assess streamflow sensitivity to climate and land cover change.
How many independent climate models are there? (How) can we reliably estimate uncertainty in future predictions and projections of climate? Which models to select for downscaling or impact studies?
