Protocol Certification Requirements

Required eTraining Modules by Sphere/Protocol

Before users can start logging their measurements into GLOBE databases, they must first complete the necessary GLOBE protocol training. To make these trainings more accessible, there are online learning modules that will help users meet our quality standards. There is a guide below to the specific modules users must complete before uploading data pertinent to a specific Earth sphere and protocol.


Choose the protocol within the Earth sphere that corresponds with the relevant data. The required modules within each sphere are ordered by ease of implementation.

Important: Users must first complete the Introduction to GLOBE training, regardless of which sphere/protocol they choose.
