Its not satellite data, it's the exact same data-set that NOAA provides for ocean levels; The data is from tidal sensors; the data is relayed via satellite so... technically ;). It's kind of funny the data in the table, vs the chart-data presented, some .orgs say 80mm, some say 60mm all depends on when you start counting. I'd like to see the raw data, geospatially portray it, and get a sense of the true impact; an average of a statisticcal averages, smoothed and corrected over 60 days with a self-ratcheting baseline... Not sure how valuable the data here is other than support a presupposition. -----Original Message----- From: NANOG [mailto:nanog-bounces () nanog org] On Behalf Of Chris Adams Sent: Thursday, July 26, 2018 12:01 PM To: nanog () nanog org Subject: Re: Rising sea levels are going to mess with the internet Once upon a time, William Herrin <bill () herrin us> said:

I *really* want to understand the technology that lets a satellite hundreds of miles in the sky detect a 3mm change in average global sea level between the start and end of the year with an error bar that grows to only 4mm over a quarter of a century.
Well, you must not *really* want to understand, since there's a "Learn more" link to follow on the above page that (after a couple more clicks) would lead you to this page that has some explanation: https://www.aviso.altimetry.fr/en/techniques/altimetry.html -- Chris Adams <cma () cmadams net>
