NASA GLOBE Land Cover Challenge 2022: Land Cover in a Changing Climate

The Global Learning and Observations to Benefit the Environment (GLOBE) Program invites you to take part in our upcoming Land Cover Challenge: “Land Cover in a Changing Climate.”

The photos you take using The GLOBE Program’s GLOBE Observer app document the current land cover and may also show evidence of land cover or land use change in the area. We especially encourage you to look for places you know have changed (or where you know change is coming), and put any information about the reasons or timing for that change in the field notes section. While existing land cover databases (such as the 50-year record from the Landsat satellite) may be able to indicate where change is happening, they don’t always include the reasons why those changes occurred, so any local, on-the-ground knowledge you share with us can be especially helpful.

Celebrate World Oceans Day with Sounds of the Sea

Ryan Vandermeulen (616) and his brother have merged ocean color data with music to create a sonic tour of the ocean.

First air-LUSI Operational Flight Campaign Begins

The airborne Lunar Spectral Irradiance (air-LUSI) mission, led by Kevin Turpie (616/UMBC), has begun its first operational flight campaign at NASA's Ames Flight Research Center. A collaborative project between NASA, NIST, USGS, and McMaster University, air-LUSI will help characterize the Moon as a reference standard for calibrating satellite instruments used to study and monitor the Earth’s environment and climate.

APOLO-2022 Conference –– Silver Spring, MD

Register for the Advancement of POLarimetric Observations (APOLO) Conference August 9-12, 2022.


The Ocean Ecology Laboratory conducts research on ocean ecosystems and the interactions between Earth's chemical cycles and life. The Laboratory also manages "ocean color" data from NASA satellite sensors. Sediment, dissolved chemicals, and marine microorganisms called phytoplankton affect the colors of sunlight reflected off the ocean, providing a way to monitor ocean ecosystems from orbit.

The Laboratory works to ensure the accuracy of ocean-color data and make it available to users across the world. Scientists use the data to study fundamental issues such as the global distribution of phytoplankton, the storage of carbon in the ocean, and the role of the oceans in climate change. Laboratory personnel also participate in research cruises in collaboration with other researchers funded by NASA and assist NASA Headquarters in developing future earth-observing missions.
