About GEMM 

The Global Environmental Measurement & Monitoring (GEMM) Initiative is an international project of Optica and the American Geophysical Union (AGU) seeking to bring together science, technology, and policy stakeholders to address critical environmental challenges and provide solutions to inform policy decisions on greenhouse gases (GHGs) and air and water quality.

GEMM Centers are currently established in Scotland, Canada, China, New Zealand, and the United States in the San Francisco Bay Area and Midwest. GEMM is open to new collaborations as we build a global network. 

We are bridging the gap

between policymakers, modelers, and technology for improved environmental and climate change impact planning. GEMM is engaging multidisciplinary regional centers and leveraging experts already in place at academic institutions worldwide. These centers and experts are focusing on creating and sharing new measurement technologies and climate models, all to enable better government and commercial industry decision-making. 


GEMM Centers are multidisciplinary regional centers that leverage experts and membership already in place at academic institutions worldwide.

GEMM engages with policy makers to address environment policy issues in their specific regions.

The GEMM Initiative is supported by Optica and the American Geophysical Union.

GEMM utilizes the global operations of both societies to convene meetings and facilitate data sharing and greater collaboration.
