November 16, 2016

Sentinel-3a is part of a fleet of satellites and was launched in February 2016 to observe Earth's oceans, land and atmosphere. It contains a suite of advanced instruments powered by solar panels. They record different measurements including sea level, temperature and colour. The data is helping us better understand our changing climate and El Niño, a climate cycle that influences the likelihood of extreme weather.

What do we do when we have collected all possible data like this? What's next?

i think its very good

We should be leaving some of the world intact without human intervention - then we wouldn't need machines like this.

i think we should protect our world becase we just have one. :)

Maybe this can finally convince the world that climate change is real.

People need to wake up to he urgency of climate change. If they do not, it could mean the end of life as we know it! That's where satellites like Sentinel-3a come in: if we have more data, we can prove that climate change is a massive problem.

super invention to make the world a better place. is there anything wrong with it? where did you get the idea from?..................

We need to start carimg for the environment! If data can show people the damage they are doing, then lets broadcast it now.

The climate event El Nino has a drastic effect on marine life starting from phytoplankton. The equator helps us predict what impact El Nino might have on the ecosystem.

it's good that we have a new satellite to get information.

Thanks for an informative exhibit on how satellites can provide data on anthropogenic climate change. I would love to see more!

Satellite data is important because you need to know the weather.

some things should be left uncovered
