The GLOBE Observer app enables you to make observations of your environment. GLOBE Observer is the app of the Global Learning and Observations to Benefit the Environment (GLOBE) Program. The GLOBE Program is an international science and education program that provides students and people of all ages 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. By using the GLOBE Observer app, you contribute scientific data to your community, students and scientists worldwide, including researchers at NASA, NOAA, and other science research institutions. GLOBE Observer allows all users to contribute observations of clouds, mosquito habitats, land cover, and trees. Trained and certified users can also use the app to submit additional environmental measurements from all GLOBE protocols. GLOBE Clouds allows observers to make regular observations of Earth’s cloud cover and compare them to 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.

Climate change will impact where and how humans live. As tides rise and storms intensify, humans will be forced to adapt to the changing environment and increase resiliency by learning more about local impacts of rising tides and intensified storms. The Coastal Observer App encourages citizens to become active in monitoring weather and water locally, and will help researchers build a pathway for a sustainable future. The citizen scientists may choose from 4 activities: 1) basic environmental observations by sharing how the current setting makes you feel. 2) weather observations to document the current weather and its impacts. 3) water level to document where the water levels are and how this might impact infrastructure, life, or property. 4) water quality to document how our environment is impacted by human practices. Observing Weather Events Weather events can have devastating effects on local communities. Using this application, the observer can make note of stormy conditions and its associated affects. This information will be documented through photographs and user documentation. Measuring Water Level If there is an installed and fixed water level gauge near you, feel free to use that gauge to enter your water level. For help locating existing gauges, please visit this link. If there are no installed, fixed gauges, you can report a value from a nearby automated gauge at the time of your observation, or simply take a picture to document the water level visually. NOTE - Never attempt to measure water levels during unsafe conditions or without proper training. Monitoring Water Quality Users may use a Secchi Disk to make manual observations of water clarity. For more information, visit the Secchi Disk Project at www.secchidisk.org Coastal Observer for Schools Schools can easily include the Coastal Observer App in their curriculum. Educators can utilize the app to teach reading water levels or using a Secchi Disk to increase environmental awareness in students, while also providing the opportunity to express feelings about water and weather events. The project runs on the SPOTTERON Citizen Science platform for participatory research and awareness building.
