GLOBE Observer invites you to make observations of the Earth around you. Observations you collect and submit with this app are designed to help scientists better understand satellite data collected by NASA from space.

The current version includes four capabilities. GLOBE Clouds allows observers to make regular observations of the Earth’s cloud cover and compare them to NASA satellite observations. With GLOBE Mosquito Habitat Mapper, users locate mosquito habitats, observe and identify mosquito larvae, and reduce the potential threat of mosquito borne disease. GLOBE Land Cover is designed to allow users to document what is on the land (trees, grass, buildings, etc.). GLOBE Trees asks users to estimate a tree’s height by taking pictures of trees with their device and answering a few questions. Additional capabilities may be added.

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.

What’s New

Version 3.0

The GLOBE Observer app now includes the Clouds, Mosquito Habitat Mapper, Land Cover and Trees tools in eleven different languages. This latest release also includes various bug fixes and enhancements, improved compass performance, and support for off-line data collection.

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!

Works well mostly

I’ve been using the app for cloud observations for about 2 months. It consistently works well and smoothly for the most part with easy to follow guidelines on making the observations. I am reducing the rating by 2 stars: 1 off for the cloud observation chart. I use an iPhone. When I try to open the chart, the cloud photos flash in their assigned boxes for an instant and then disappear. And 1 off for the fact that I tried to contact support twice about 2 issues and only got automated replies which were not helpful.

Cloud chart display issues

I just downloaded the app and the cloud ID chart isn’t loading properly. The images showing cloud types load for a fraction of a second and then disappear. I’m on an iPhone 6s with iOS 15.2. Thanks.
