Between capturing Instagram-worthy images of blooming cherry blossoms, why not snap a few photos for NASA?
Citizens scientists can help investigatehow carbon moves through ecosystems by using your smartphone to measure tree height.
NASA’s GLOBE Observer app provides a step-by-step guide for people to collect and submit data on their surroundings—including Earth’s cloud and land cover and mosquito habitats.
The new GLOBE Trees feature, meanwhile, lets users record tree height by simply tilting their phone up and down to align the screen with the top branch and base, then pace off the distance to the woody plant.
Observers can measure one tree or one hundred trees—there is no pressure or obligation.
Data points, along with a GPS tag of the tree’s location, are sent back to NASA and stored in a database.
