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 ...

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, ...
