What we're really trying
to find out is how do things change over time?
They change slowly over time as a whole system.
So we're seeing millimeter level trends over the course
of many years.
However, the ocean is very dynamic,
and knowing what's happening in the regional space
is very, very different.
And it changes within hours.
So really understanding what's happening within hours
is very, very important.
So even with the best models that have now been created,
they still need data to actually
inform and train those models.
Understanding what's happening with the full water cycle,
whether it's freshwater, coastal,
and the oceans is very, very important
to be able to literally,
affect what's happening with agriculture,
the cleanliness of our water, the availability of our water,
and also the economics, of of what's happening with the,
displacement of water and where it's needed.
And there's too much of it in short amounts of times, which
caused disasters like floods to very on the opposite scale,
where there's too little and we have droughts
and, tremendous, impacts with the lack of water.
Having a measurement
really is important towards
understanding what's happening with the ocean,
both in real time but also in terms of forecasting,
because it really impacts how we live in everyday life
along the coast,
but also in terms of what happens in the ocean
and on the ocean, whether it's with shipping, navigation,
and especially with how the ocean is interacting
with the atmosphere
towards these sorts of extreme events like hurricanes.
I really hope like Sentinel 6B data are going to be,
used by people all around the world
to improve, our forecast, whether it's for El Nino, La Nin
or hurricane intensification or for coastal communities
to better plan for the for the future.
Sentinel-6B is the latest in a long generation
of satellite altimeters.
Provides really good information
about how sea levels
are changing
now, but also compare them to how they've changed in the past.
So we can see exactly how things are evolving over time
as Earth changes in our oceans change.
So the way the Sentinel-6B measures is
it sends a radar signal down
to the surface of the ocean and measures
how long it takes that signal to get back to the satellite.
And from that, we can really get a very accurate measurement
of how sea levels are changing locally and on a global scale,
down to about a one inch accuracy.
