A wave train entering into the North Sea, seen by #Sentinel1 on 12 August. I am guessing it's tidal-related, but I have never seen this kind of signal in this region in SAR data before, pretty cool 😎 @jowilliams.bsky.social
A satellite image of the southern North Sea, showing land in white and the sea in shades of grey. A semicircular pattern between UK and France can be seen in the English Channel. White dots in the sea are windmills and ships.

Chuffed to bits that Tom is now a colleague. Exciting times ahead!

I’m delighted to share that our latest research has just been published in HESS. We developed an unsupervised workflow to estimate river surface velocities from videos. Testing on 11,000+ videos against 274 gauging measurements showed excellent agreement. hess.copernicus.org/articles/29/...

First cloud-free optical satellite imagery from @planet.com show the destruction of Dharali village in Uttarkashi, Uttarakhand, India. Unfortunately the source area in the mountains is still obscured by cloud and so the ultimate cause is still speculative. 🧪⚒️

Incredible story. Hg production fell to zero in 2020 but now rising (illegally it seems) to propel gold extraction in the Amazon financed and facilitated by Mexicos drug cartels… Horribly toxic - I thought mercury use had been nearly eliminated.

Here's a fun anomaly for an inland flood risk map. It's genuinely very helpful in places: check-long-term-flood-risk.service.gov.uk/map But it's based on scans of the ground, & the processing gets confused sometimes. I think the 4-storey pitched roof of this hospital is probably safe from flooding!
Part of the "check long term flood risk" service map, with settings at future, and 20cm depth, showing blue on a large area in a grid shape.satellite view of the same building from google maps. Some of the roof is flat but the shadows indicate it is mostly pitched.

So the Cunliffe report is out today. Couple of first takes: 1. It seems comprehensive - lots of concise detail but 2. Nothing about flooding (that I can see) which in most urban areas is intrinsically linked to sewage systems and water utilities. assets.publishing.service.gov.uk/media/687d5c...

I see NERC is reverting to a policy from 15(??) or more years ago on resubmissions. I suspect it will be counter productive to NERC workload - as checking for this will not be easy, and building on this - it looks quite easy to game/work around. So - I’m left with why bother (with the new policy!)

There have been claims that NOAA/NWS did not foresee catastrophic TX floods--but that's simply not true. This was undoubtedly an extreme event, but messaging rapidly escalated beginning ~12 hrs prior. Flood Watch mid PM, "heads up" outlook late PM, flash flood warnings ~1am.
