Educators from the GLOBE Mission Earth project participated in a community of practice (CoP) led by NASA Langley Research Center to refine how students interact with NASA's land cover data from MODIS, Landsat, and Sentinel-2. The CoP focused on data collection, curriculum integration, student research, and validation to refine how students interact with NASA's land cover data.

#QuickGLOBETip for making GLOBE Trees observations!
How should you measure the tree you are observing? Tip #3: When searching for a tree, find a spot 7ā15 meters (25ā50 feet) away from the tree that allows you to clearly see the top and bottom.

šTitle: Evaluating Satellite Land Cover Classification Accuracy Using Participatory Remote Sensing
š„Authors: Aren Finelt, Russanne Low, and Peder Nelson
This study evaluated satellite remote sensing accuracy when classifying complex urban environments. By comparing datasets from satellite-derived land cover tools and ground-based citizen science observationsāincluding the GLOBE Observer app in Hato Rey, Puerto Ricoāthey found that several satellite datasets frequently overgeneralized land cover as entirely urban, missing water features and vegetation.

Help GLOBE reach 2 million satellite matches by April 2027!
Submit your Cloud and Land Cover observations in the GLOBE Observer app. With every observation that aligns with satellite data, you will receive an email from NASA with matching satellite imagery so you can compare your view on the ground with whatās seen from space.
With 1,726,900 satellite matches to date, we have only 273,100 to go!

Is it hotter on the road or the sidewalk? Is the park cooler than the lake shore? Take a quick surface temperature measurement and share your findings on the GLOBE Observer app. Your data can help scientists understand the impact urbanization has on the Earthās surface temperature and how the surface temperature changes the dynamics of the Earthās atmosphere.

šTitle: Evaluating Satellite Land Cover Accuracy in a Suburban Environment Using Citizen Science: New Hyde Park, NY
š„Authors: Nandini Khaneja, Peder Vernon Nelson, and Russanne Low
This study compared datasets from satellite-derived land cover tools and ground-based citizen science observations including the GLOBE Observer app in New Hyde Park, New York. Findings indicated that field documentation and community knowledge improve land cover assessment in suburban regions to account for frequent over-generalization of developed land cover and underrepresentation of tree canopy made by satellite observations.
