History of GLOBE Protocols

With relation to GLOBE Campaigns and Projects

GLOBE Protocols have been part of the NASA GLOBE Program since its inception in 1995. The first 11 protocols included air temperature, tree height, water temperature, and soil characterization. These first protocols, and all protocols implemented thereafter, represent the four Earth spheres: Atmosphere, Biosphere, Hydrosphere, and Pedosphere. The protocols within the four Earth spheres help support and promote environmental education, awareness, and literacy for GLOBE students, teachers, and the entire worldwide GLOBE community. Over the years, NASA and GIO, with the help from the GLOBE community, have created and implemented over 45 unique scientific protocols. These protocols include connections to several learning activities and programs, such as GLOBE Measurement Campaigns, Data Challenges from GIO and GLOBE Observer, and Intensive Observation Periods (IOPs). 

Below is a timeline of the GLOBE Protocols that have been implemented over the past 27 years of the NASA GLOBE Program! In some cases, we have included connections to other GLOBE program launches and initiatives. Please let us know if we missed anything, or you, the GLOBE community, would like to add anything to the timeline! Enjoy!

As the first of many, the GIO staff hope to produce science-focused blogs that inform the GLOBE community on science-related projects, updates, and curiosities. We hope you all find these fun and informative! 


Have a suggestion on what we should write next, feel free to reach out to the GLOBE Science Team at globescience@ucar.edu.

What a great timeline!

I thought the Special Eclipse feature debuted for the 2017 North American Eclipse?  Have I forgotten a step?
