Further proof that radar remains the coolest remote sensing technology.
Note the quote from the article: "The measurements included a wave height exceeding 1.5 feet (45 centimeters), shown in red in the highlighted track"
45cm max heightdiff on an image 15 degrees long taken from space. Amazing.

Just realized that the NGS Webinar series hasn't been broadcast since April. Usually it's done once per month.
It doesn't seem like it'd cost very much to produce, and public outreach is actually useful, despite not bringing in any quick bucks. #geodesy

I'm getting flaky performance today from geodesy.noaa.gov . Will load once, then time out the next time I try.
Also, it looks like cddis.nasa.gov is behind an earthdata login now?!
Probably just me but seems like lots of breakage in GNSS data sources at *.gov ...

I'm looking for any info about how & why it was decided to use the Space Shuttle do create SRTM in 2000
A few questions I have:
- How of the world had we mapped in 3D before 2000?
- Why the Space Shuttle over a dedicate satellite (or pair of satellites)
- How the data was processed

NGS are the world standard for a lot of what they do. The long term planning, the research translated into continent-scale products, the tooling/data made available for current geodesy, the public outreach.. nothing like that will come from the private sector and all of it is of huge value.
SCOOP from me: the mass exodus of employees from NOAA is decimating a tiny office that literally keeps our measurements of latitude and longitude accurate — and, former employees tell me, endangers the science of how the US understands global measurements:
Trump Cuts Are Killing a Tiny Office That Keeps Measurements of the World Accurate
A tiny but crucial agency that maintains physical coordinates like latitude and longitude in the US is struggling as the Trump administration forces out federal employees.

This was floated back in the Trump I. It was a bad idea then and it's a bad idea now.
Landsat provides far more value when it is available free of charge, simply because the usage of the products is much higher. Usage benefits citizens via better modelling and monitoring of natural resources.

Landsat could use your support. The mission's 50+ year data continuity is at risk. If you believe contacting elected representatives does anything, now would be a good time to apply pressure. 🛰️📡

The atomic spectral lines in this app come from the NIST atomic spectroscopy group, which has provided the world with spectroscopic measurements for 120 years.
Today we got word that the federal government is laying off the entire group. 🔭🧪

When I heard Musk say this on Tuesday, my assumption was that it was a programming issue. Because I can code and have written to databases and because I am familiar with other examples of default values being misinterpreted.
Yet somehow Musk isn't.

Within NOAA is the National Geodetic Survey, which would be harmed by this. Tracking how the positions on the earth shift requires measurements from throughout the world.
What harm will be done if the NGS is cut off from the IERS, or from collaboration on new North American reference systems?

Trump administration orders NOAA scientists to halt all international work. Staff were told to stop meetings, discussions, emails with foreign colleagues. Freeze affects travel, virtual meetings, and collaborations until political appointees review them. 🐢🌍🧪🦑

NOAA is also responsible for a huge number of global public goods - not just for the US. NOAA data is used around the world for all sorts of Earth and climate sciences, and in disaster relief/humanitarian aid operations. Huge disaster for US soft power and a bigger disaster for real people.

A knock-on effect of Musk's closure of USAID is that the Famine Early Warning System (FEWS) is offline. Until this weekend it was one of the best resources into the food security situation in large parts of the world, & provided (as its name suggests) critical foresight into looming famine.
