What is GLOBE Observer?

  • A citizen science app allowing volunteers in GLOBE countries to take observations and contribute to the Global Learning and Observations to Benefit the Environment (GLOBE) community
  • A way to collect data to track changes in the environment in support of Earth system science research, and interpret NASA and other satellite data
  • An open data set available to scientists, and supporting students of all ages in doing real scientific research through the GLOBE Program

Download the app and follow the instructions to get started. Always follow guidelines from your local officials, and only participate in GLOBE activities or use the GLOBE Observer app if it is safe to do so.
