GLOBE Observer invites you to make environmental observations that complement NASA satellite observations to help scientists studying Earth and the global environment.

By using the GLOBE Observer app, you are joining the GLOBE community and contributing important scientific data to NASA and GLOBE, your local community, and students and scientists worldwide.

New and interested users are encouraged to go to to learn more about the GLOBE program. A one-page summary of GLOBE Observer is also available.

The GLOBE Observer App currently includes three main protocols: Clouds, Mosquito Habitat Mapper, and Land Cover. Future versions of GLOBE Observer will add additional tools to help you further contribute to the global scientific community.



By photographing clouds, recording sky observations, and comparing them with NASA satellite data, you can help scientists gain a new perspective on clouds that satellites just can't provide: from the ground looking up! This new perspective will help refine satellite-derived models and enhance scientific understanding of Earth's atmosphere.


Mosquito Habitat Mapper

By identifying potential breeding sites for mosquitoes, sampling and counting mosquito larvae, and by using optional equipment to examine, photograph and identify the genus of your specimens, you will be enabling scientists to verify predictive models of mosquito population dynamics. In addition, public health authorities can use your observations to inform where, when, and how to intervene in their communities to reduce disease risk.


Land Cover

By photographing and classifying the land cover over an area the size of a soccer field, you will be assisting those scientists working to enhance global maps of land cover use.  Your observations will contribute to new maps with a finer spatial resolution than is possible using satellites alone. Land cover is critical to many different Earth processes, and is of interest to a wide variety of scientists and decision makers.
