#nokings San Diego Harbor today.

Nothing to see here, just delivering a dinosaur in Solana Beach .

Second step, eat 🍦 while walking home along the board walk.

First step, take my favorite 🚌 (30) to PB ice cream.

Always nice to be in a country that knows how to spell my name 😀

We had beautiful weather for Thanksgiving - this was the sunset that night in Pacific Beach.

To my SD followers, I grew up in PB (Kate Sessions, PBJH, MBHS), but moved to Colorado in 1990. I enjoyed Colorado, but honestly never saw the need for seasons. I've recently moved back to PB -and am enjoying living in the slow lane, getting around by walking, biking, and taking the bus/trolley.

Geodesists have definitely been tracking the rate of ground deformation in the southern US with GPS/GNSS. Not too many people in the US are using GPS/GNSS as a tide gauge though. A few years ago I did look at the signal from Hurricane Laura. agupubs.onlinelibrary.wiley.com/doi/full/10....

I also maintain gnss-reflections.org - which has a link to the biggest and best compilation of tide gauge results using GNSS reflectometry (Simon Williams and PSMSL). You can also give a look to how the method can be used to measure soil moisture, snow accumulation, and vegetation water content.

Can you use reflected GNSS signals to measure ice and surfaces? @icesheetmike.bsky.social Thomas Nylen and I summarized results in Greenland - tc.copernicus.org/articles/14/...
November 21, 2024 at 5:59 PM
When I retired, I started building an open source software package (see my bio for the link) that takes GPS/GNSS signals that reflect off water/ice surfaces so you could use a traditional geodetic sensor as a tide gauge. This example is from Greenland. 🌊 and 🧪❄️

The Crystal Pier Hotel in PB is flying the Thin Blue Line. Not sure the constitution says that if you rent a room you get to fly a flag over a hotel... but when I asked that seemed to be their policy. en.wikipedia.org/wiki/Thin_bl...

🌊 GNSS data can be used to measure tides and lake/river levels. Simon Williams will be giving a review talk on this topic in a few weeks. Sign up if you would to watch it live. Abstract can also be found at the site. bit.ly/3O4uyPG
