The CDIAC data archive ceases operation at the end of September 2017. The data collected over 30 years of CDIAC operation is transitioning to new archives. ESS-DIVE is managing the transition, and is hosting an interim version of the CDIAC website that provides access to the CDIAC data. If you have any questions about ESS-DIVE or the data transition, contact firstname.lastname@example.org.
The new archive for the CDIAC data will be ESS-DIVE, except in the specific cases mentioned below. The Oceanic Trace Gas data have been transitioned to the new Ocean Carbon Data System (OCADS) operated by NOAA’s National Centers for Environmental Information (NCEI) at https://www.nodc.noaa.gov/ocads/. The Total Carbon Column Observing Network (TCCON) data are being transitioned to Cal Tech at http://www.tccon.caltech.edu/. HIAPER Pole-to-Pole Observations (HIPPO) data are transitioning to the NCAR Earth Observing Laboratory at https://www.eol.ucar.edu/data-software.
