GLOBE Observer

The GLOBE Observer citizen science app allows volunteers to take several different kinds of data using their cell phones, and join the Global Learning and Observations to Benefit the Environment (GLOBE) community. The data are used in multiple projects to track changes in the environment in support of Earth system science research. The resulting open data set is available to scientists, and used by students of all ages doing a variety of research projects through the GLOBE Program.

Mosquito Habitat Mapper has a flying mosquito above a wave of water, with a mosquito larvae suspended below.
Trees shows a forest of diverse trees types.
Total Eclipse cleverly uses the “C” in “Eclipse” as an eclipse, with the “c” as the star in bright white surrounded by radiating corona and the circle of black in the center as the planetary object partially blocking the star.
