Today at #GeoForGood21 we previewed a forthcoming ~OPEN SOURCE~ textbook on Earth Observation. The chapters cover a huge breath and depth of topics (change detection! urban heat islands! fire monitoring!) with #EarthEngine code that walks through implementation.

Going to AGU this year? Interested in large scale geomorph and riverbank migration? Come check out my talk! EP34A-08, Wednesday at 3pm CST

After some interest in my last #AGU21 tweet, here is my Google Earth Engine App that I made for these river meander gifs. The code behind it is hugely simplified from the methods for our dataset, so don't be shocked if you break it. tedlanghorst.users.earthengine.app/view/riverbank…

How are nutrients, algae, and dissolved organic matter related? Analogies with pizza say it best! Chat with me at my poster TODAY (H15V-1297) or shoot me a message to chat online !#AGU21 #sketchyourscience

A great visualization of the Landsat record and a reminder of the variable data quality in many Landsat-based data products.

Thanks Dr. Nicholas J. Kinar 🇺🇦! Here's my favorite figure- OpenOBS shows highly linear response from 0-1000 NTU with similar uncertainty to commercial sensors. This means calibrating to site-specific sediment only requires a few samples.

This is great! Thanks to Samapriya Roy, PhD. for this and the entire #GEE community dataset website. samapriya.github.io/awesome-gee-co…

While myself and the Toolik Field Station EDC technicians have been keeping the Naturalist Journal going through the winter on top of our other work it is great to have our Naturalist back. Day one back up at Toolik he found a recently born muskox. uaf.edu/toolik/edc/jou…

New Paper: Global Observations of Riverbank Erosion and Accretion From Landsat Imagery Ted Langhorst & @uncglobalhydro doi.org/10.1029/2022JF…

And now...(drumroll)...the fully deployed reflector! This 3.5 m diameter structure made from knitted material is the eyes and lens of the radar and allows the satellite to capture images of what’s happening on Earth. 😍💛🛰️ #SAR #Satellite #StrongerTogether #Earth

A whole new view 🤩 🌊 First taste from the SWOT mission shows Earth’s water in higher definition than ever before. The spatial resolution of SWOT ocean measurements is 10 times greater than sea surface height data gathered over the same area by seven other satellites combined.

A few more views of the raging St. Louis River at the Swinging Bridge in Jay Cooke State Park this evening The river is in major flood stage — though still about 3 feet below the all-time record set in 2012 (when the bridge washed away)

Good luck, Rajaram and team! First OpenOBS deployment in Asia, as far as I know.

New piece in ARCUS Witness Community Highlights about a project I've been working on this year, called SILT! Check it out here: arcus.org/witness-the-ar… This Fresh Eyes on Ice -adjacent project is testing (1/3)

Had lots of fun making this viz for the #30DayChartChallenge and am so grateful for all the feedback and help from USGS Data Science ! Excited to keep working on streamflow estimation from satellites, especially with future SWOT data!

Had a chance to install OpenOBS sensors (thanks to Ted Langhorst) in the macro-tidal marshes of the Gulf of Morbihan, France with the help of UBS_universite scientists. Been a flash of a few days getting to know fellow coastal scientists #NSFASI and reading new environments

🚨 New Paper Alert!🚨: Excited to share my latest work in nature on river avulsions—catastrophic shifts in river courses that threaten millions worldwide. We've uncovered new rules that govern when and where avulsions occur. nature.com/articles/s4158… 🧵(1/12)
