New Climate Satellite Measures Sea Level Rise

This entry was posted in Space Administration on by .

A satellite scheduled to launch from California later this month will measure sea level rise and provide other crucial data to scientists who study how global warming is affecting the Earth’s oceans.

Melting ice has already caused sea levels to rise by about 8 inches since 1880, and the trend is accelerating. The Earth’s oceans have soaked up the vast majority of the extra heat, and about one quarter of the extra carbon dioxide, that humans have generated by burning fossil fuels.

Earth Satellite Joins NASA Fleet to Monitor Sea Level, Improve Weather Forecasts

Learn about the mission and find out how to make classroom connections to NASA Earth science ‘plus explore related teaching and learning resources.

In the NewsA new spacecraft that will collect vital sea-surface measurements for better understanding climate change and improving weather predictions is joining the fleet of Earth science satellites monitoring our changing planet from space. A U.S.-European partnership, the Sentinel-6 Michael Freilich satellite continues a long tradition of collecting scientific data from Earth orbit. It’s named in honor of NASA’s former Earth Science Division director and a leading advocate for ocean measurements from space.

SpaceX will boost a new NASA satellite and land with a boom this weekend

The next SpaceX Falcon 9 launch is slated to carry a new NASA and European Space Agency satellite to orbit as soon as Saturday.

The payload will be the Sentinel-6 Michael Freilich satellite, which is the latest in a series of satellites that have provided critical data about sea level rise and climate change for almost three decades. It’s named for the former director of NASA’s Earth Science Division, Michael Freilich, who is considered a pioneer in conducting oceanography work from orbit.

What’s going on with sea level rise?

One longstanding concern regarding global warming is how fast sea levels will rise. It is a very closely monitored topic since it impacts so many people that live in coastal areas throughout the world. The current average rate of sea level rise worldwide is about 3.3 mm per year. Most climate researchers expect that rate to increase in upcoming years.

So the rate of sea level rise is much different from spot to spot. Learn all about the measurement and behavior of sea level from this NASA article below. It is well worth the read!

Earth’s global sea levels are rising ‘ and are doing so at an accelerating rate. Waters in the ocean are expanding as they absorb massive amounts of heat trapped by greenhouse gases in Earth’s atmosphere. Glaciers and ice sheets are adding hundreds of gigatons of meltwater into the oceans each year. The land surface along the coasts is also creeping up and down, affecting relative sea level rise. People are feeling the impacts, as seemingly small increments of sea level rise become big problems along coastlines worldwide. Mean Seal Level from 1993 to 2020 has been rising about 3.3 millimeters per year. The number is calculated by averaging sea surface height data from a series of satellites: TOPEX/Poseidon, Jason-1, OSTM/Jason-2 and Jason-3. The data record continues with the launch of Sentinel-6 Michael Freilich. Credit: NASA

This new ocean-mapping satellite will help us all understand the impacts of climate change

Examining coastal sea rise, tracking underwater ocean waves and adding to long-term data about climate change will be the main scientific return of the Sentinel-6 Michael Freilich satellite mission, officials said in a press conference.

The satellite is expected to launch Nov. 10 on a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida. For now, spacecraft personnel expect SpaceX will be able to resolve a rocket gas generator issue that stopped a GPS satellite launch for the U.S. Air Force aboard another Falcon 9 on Oct. 2, Tim Dunn, launch director of NASA’s launch services program, said in a virtual press conference broadcast Oct. 16 on NASA Television.
