“Whether it’s since 1985 or 2000, we see this greening of the Arctic evident in the Landsat record.”

“Science and reliable data need to be at the heart of policy decisions around the globe if we are to tackle climate change and other serious environmental challenges facing our world. It is vital that we share the trusted data that comes from Earth observation so citizens, scientists, and political leaders everywhere can most effectively work together to meet these most difficult challenges.”

“The availability and accessibility of remotely sensed digital imagery obtained from Landsat satellites allow coastal scientist—and more importantly community members—the opportunity to map, evaluate and continuously monitor shoreline movement at regular intervals given the unprecedented pace of Arctic climate change.”

“Without Landsat’s long record, studies like ours would be impossible to undertake, because we don’t have a time machine to go back to the 1970s and 1980s and see how Turkey’s glaciers were doing then. Using Landsat and commercial satellite data together, we can map glaciers with high accuracy. It’s a powerful combination for studying the Earth from space.”

“Satellites like those in the the Landsat program – which celebrates its 50th anniversary on July 23, 2022 – have become crucial for pinpointing urban risks so cities can prepare for and respond to extreme heat, a top weather-related killer.”

“From a valuation standpoint, Landsat is an extremely valuable public good just in its direct use—let alone the economic value of all the indirect uses built on the direct data.”

“The quality of the Landsat 8 images is simply amazing!”

“Landsat optically observes Earth’s surface through measurement of reflectivity and temperature in polar ice and oceans, as well as across the Earth, and these are two key geophysical parameters for measuring and modeling surface energy balance.”
