ICESat-2's laser instrument measured the heights of trees🌲, tall buildings🏙️ and houses🏘️ along a path between Bernal Heights and Telegraph Hill, plus the San Francisco (San Phrancisco?) Bay.

It’s not all ice and land elevation…the “C” in ICESat-2 stands for clouds☁️! Today's #PhotonPhriday  takes us above the Pacific, where #ICESat2  took measurements not only of clouds, but smoke from this fall's fires🔥 in Sonoma County, Calif. (h/t Stephen Palm for the image)

After 🔟 years of surveying Earth's polar ice, Operation#IceBridge  ✈️ wrapped up its final flights this week in Antarctica! 🎉

On Tuesday, the team flew over the Lilie, Black, Canham and Rennick Glaciers.

Do you have a favorite #IceBridge  memory? 💙✈️

ICESat-2's science mission focuses on measuring our planet's frozen polar regions, but the satellite is on all the time - capturing trees, cities, and Earth's stunning geologic formations .

California, here we come! Thousands of Earth and space scientists are packing their bags and poster tubes for #AGU19  next week in San Francisco🌉 - but here's a sneak peak at the hilly city courtesy of our height-measuring #ICESat2 🛰️ & #PhotonPhriday !

From yesterday's #IceBridge  flight: A tabular iceberg can be seen on the right, floating among sea ice just off of the Larsen C ice shelf. The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf.

2018 Arctic sea ice minimum extent tied for sixth lowest in the nearly 40-year satellite record

Operation #IceBridge  ✈️ helped pull back Greenland’s curtain of ice ❄️to identify an impact crater from a meteor thousands of years in the past.

An iceberg about the size of Delaware has split off from Antarctica - scientists wonder: what happens next?

Enjoy this photo of the extended sunrise near the North Pole, courtesy of today's #IceBridge  flight.

Wow, it’s been amazing to see what a splash our photo of a tabular Antarctic iceberg, by #IceBridge  ’s Jeremy Harbeck, has made. Fly toward the berg with 's DC-8 forward camera. More:

We're ready for launch! Can't wait to launch into orbit to measure our planet's ice! 🚀🛰🌐

From #IceBridge  Alaska: A higher altitude view of Icy Bay, in the Wrangell-Saint Elias Wilderness. Just a century ago, this body of water was covered in ice.

A possible crater 🕳 caused by a meteor impact ☄️ lies buried beneath more than a mile of ice ❄️ in Greenland. It’s more than 22 miles 📏 wide, which would make it the 22nd largest impact crater ever found on Earth.
