The Technology and Architecture Standing Committee is tasked with facilitating the development of the EarthCube technology, including stewardship of the ongoing architecture. The Technology and Architecture Standing Committee occasionally coordinates with the Science Standing Committee to ensure that scientific research needs for technology drive the development of the EarthCube architecture.

The TAC hosts regular 1 hr long telecons monthly on the first Thursday  at 1:30 pm PT/ 4:30 pm ET. All are welcome to join. Call-in information and the full schedule are available on the Calendar. Notes from past meetings are available in the TAC Google folders.  
Co-Chair/Leadership Council Representative: David Fulker, formerly OPeNDAP/UNIDATA  (September 2019 - May 2020)
Co-Chair: Ruth Duerr, Ronin Institute  (January 2018 - December 2019)

A cohort of data repositories is being assembled to apply for CoreTrustSeal certification as part of the American Geophysical Union Coalition Enabling FAIR Data Project. CoreTrustSeal certification demonstrates to a repository’s users and funders that they have been evaluated by an independent authority and endorsed for their trustworthiness.  If you are interested in becoming a member of this cohort, please send an email to Rebecca Koskela (

TAC Working Groups
The work of the TAC is carried out by members of various working groups listed here.  TAC Working Groups are focusing on Architecture, Testbeds, Gap Analysis, Standards and Standards Bodies, Technologies, and Use Cases (to guide cyberinfrastructure requirements). Final Working Group reports (when completed) are available from the TAC working groups page.
