In GLOBE, there are two major perspectives on the global environment – the spheres and the Earth system. The Teacher’s Guide and the new sphere pages build on the approach that examines Earth as the atmosphere, hydrosphere, biosphere, and pedosphere. The study of Earth System Science focuses on the cycles that connect the spheres – the Energy, Water, and Biogeochemical. The Honor Roll provides recognition of those who report in depth in one area or another. There are three honor rolls recognizing Atmosphere measurement reporting; one for Hydrosphere;, and two each for Biosphere and...

Observations of daily precipitation have been a part of GLOBE from the beginning. At the start, GLOBE’s participation model was that schools would take measurement following all of the original 17 protocols. Atmosphere temperature, precipitation, cloud, and soil moisture measurements were to be collected daily at a site easily accessible to the school. A permanent installation of an instrument shelter containing a max/min thermometer mounted to a post along with a rain gauge was the expected norm with other measurements taken nearby. Daily temperature and precipitation measurements were...

As Earth science has a single uncontrolled object of study, the first rule is to take today’s data today. While ice and sediment cores and fossils can reveal past conditions, the observations that can be made right now cannot be replaced by ones taken later. This goes well with the Native American adage, “You can’t step in the same river twice.” The environment is constantly changing and doing so on a wide range of time and space scales. In a recent video post, Neil deGrasse Tyson said, “One of the great things about science is that it is an entire exercise finding what is true. You...

Consider the rain gauge used in GLOBE, CoCoRaHS, and other citizen science programs. Just four pieces plus 2 mounting screws – an inner graduated cylinder, an outer cylinder, a cap/funnel, and a mounting bracket. The area of the outer tube is exactly 10 times the areas of the inner tube and the cap/funnel, so the graduations on the inner cylinder can be spaced ten times further apart. Thus, 0.2 mm of rain fills the inner tube to a depth of 2.0 mm, which one can read. In addition, if heavy rainfall fills the inner cylinder, the rest of the rainfall overflows into the outer cylinder,...
