GLOBE Observer Data: 2016-2019

This technical report summarizes the GLOBE Observer dataset from 1 April 2016 to 1 December 2019. GLOBE Observer is an ongoing NASA-sponsored international citizen science project that is part of the larger Global Learning & Observations to Benefit the Environment (GLOBE) Program, which has been in operation since 1995. GLOBE Observer has the greatest number of participants and geographic coverage of the citizen science projects in the Earth Science Division at NASA. Participants use the GLOBE Observer mobile app (launched in 2016) to collect atmospheric, hydrologic, and terrestrial observations. The app connects participants to satellite observations from Aqua, Terra, CALIPSO, and MODIS. 38,000 participants have contributed 320,000 observations worldwide, including 1,000,000 georeferenced photographs. It would take an individual more than 13 years to replicate this effort. The GLOBE Observer app has substantially increased the spatial extent and sampling density of GLOBE measurements and more than doubled the number of measurements collected through the GLOBE Program. GLOBE Observer data are publicly available at observer.globe.gov.

917 GLOBE Eclipse: Citizen Scientist Measurements of Atmospheric Changes During Astronomical Events

The GLOBE (Global Learning and Observations to Benefit the Environment) Program is an international citizen science (CS) and education program. The program’s GLOBE Observer app guides participants to collect cloud and air temperature observations during solar eclipses. The participants are prompted to collect: - Air temperature every 10 minutes and then every 5 minutes 30 minutes before/after maximum. - Cloud information (cover, type, and height) every 15 to 30 minutes. - A land cover observation the day of the eclipse (new in 2023). This research explores: - The importance of citizen science. - The effects of the solar eclipse on clouds.
