NASA Globe Observer is a Citizen Science Tool

NASA 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. Recently NASA added a new addition: Globe Trees. App Store: Free
