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.
