GLOBE Observer invites you to make observations about the Earth around you. Observations you collect and submit with this app are used by scientists to validate, interpret, and understand satellite data collected by NASA from space.

The current version includes two capabilities. GLOBE Clouds allows observers to make regular observations of the Earth’s cloud cover and compare it to NASA satellite observations. GLOBE Mosquito Habitat Mapper allows users to locate mosquito habitats, observe and identify mosquito larvae, and reduce the potential threat of mosquito borne disease.

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. The Global Learning and Observations to Benefit the Environment (GLOBE) Program is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment.

Crashed after iPhone update


I learned to use this app so I could contribute to the data collected by citizen scientists during the 2017 eclipse. I continued to collect data for the entire summer and autumn with no problems.

The UPSIDE was the reward of the current worldwide satellite map that I could view after I submitted my data. The eclipse was mind blowing to view from the satellite view but the devastating fire season was the most interesting thing. I posted many screenshots of these things to Facebook. I also was fascinated to follow typhoons and hurricanes, and I often knew about them before they were reported in the media.

The problem came with the iPhone update I installed last winter. The camera portion of the data collection quit working correctly, also there was no way to submit a report from the ‘Pictures’ portion of the Globe Observer app. I have updated my iPhone and deleted and reinstalled the app a few times since and the app still does not work.

I am looking forward to the Globe Observer app being updated so I can contribute again. But perhaps NASA does not need this info anymore. It was fun while it lasted.

Sorry to hear about the problems. We haven't heard of too many issues with crashing - please send details to our support line so we can look into it in more detail. Thankyou!



I like the app a lot. I honestly think it’s awesome. But I did feel a little uncomfortable saying yes to giving away my location. Great app overall though!

Developer Response

Thank you for your review and contributing to GLOBE!



Terrible UI. Compass won’t calibrate at all. Shows North as being SE. The photo feature locks and you can’t escape the screen. They need to fix the compass calibration and the photo capture feature, otherwise the app is entirely useless because the data can’t be used.

Developer Response

When using the photo feature, make sure to rotate your camera in the direction indicated. Be sure you are not near buildings as they can interfere with the compass. There is a manual mode available if the compass continues to be problematic.
Please send details to us at so we can investigate further.
