📃Title: Evaluating Satellite Land Cover Accuracy in a Suburban Environment Using Citizen Science: New Hyde Park, NY
👥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.

We were excited to hear from NASA geologists Amber Turner and Megan Borel, members of the Artemis II Lunar Science team, at the May GLOBE Observer Connect webinar. Hear about how Amber and Megan worked with the Artemis II crew to prepare them for their historic lunar flyby, the science behind the mission, the key observations astronauts made, and how those discoveries could help answer fundamental questions about the Moon, Earth, and our solar system.

The results of the #ObserveLikeArtemis Challenge are in!

Inspired by the Artemis II mission, we invited the GLOBE community to take observations of their favorite features of Earth. From the 22nd of April to the 22nd of May, the community made over 16,000 observations across the spheres. GLOBE users shared a total of 284 pedosphere observations, 918 hydrosphere observations, 3,900 biosphere observations, and 11,642 atmosphere observations!

An El Niño will likely arrive later in the year, according to sea level data from Sentinel-6 Michael Freilich. The satellite—which measures the height of the entire ocean every 10 days—captured a swell of warm water hundreds of miles wide in the Pacific Ocean off the coast of South America.

📰Title: Comparison of Land Cover Classifications between Ground Observations and Remote Sensing Data in San Diego, California
👥Authors: Sophia Farber, Peder V. Nelson, and Russanne Low

This study investigated local land cover trends in San Diego, California, evaluating consistency between ground observations using the GLOBE Observer app, manual land cover classifications, and land cover maps from remote sensing sources. The findings revealed challenges when reviewing remote sensing data, with some datasets overgeneralizing urban land cover compared to other sources.

#DYK You can create an easy way to capture mosquito larvae by building a trap at home? All you need are a few simple items like a bottle, a sponge, and a few other household items. Once you’ve caught your larvae, submit your observations using the Mosquito Habitat Mapper tool in the GLOBE Observer app.
