Data Miocene

Data for the DeepMIP-Miocene Group

Data from the MioMIP1 Opportunistic Multi-Model Ensemble

Burls et al. (2021) synthesized available Miocene surface temperature reconstructions. A new synthesis of Middle Miocene terrestrial mean annual temperature (MAT) estimates can be found in their supporting information (additional excel file Table S1). Late, Middle and MCO SST estimates were compiled using published data sets, a summary of these data sets with links to their repositories has been complied in their supporting information (additional excel file Table S2). These datasets have also been archived in a Zenodo repository Note that there is a hosted at Stockholm University.

The synthesis of published Miocene SST records in Burls et al. (2021) formed the initial compilation of data for the Miocene Temperature Portal hosted at Stockholm University. This portal collates a growing list of key information about published Miocene sea surface temperature records to enable researchers to rapidly locate and evaluate datasets relevant to the study of Miocene climate change.

Acosta et al. (2023), synthesized available Miocene hydroclimate reconstructions and hydrological fields from Miocene climate simulations. Their new synthesis of early-to-middle (E2MMIO) and middle-to-late (M2LMIO) Miocene terrestrial Mean Annual precipitation (MAP) reconstructions can be found in the supplementary excel file (MioMIP_MAP_compilation) and in Zenodo repository ( The hydrological fields from the Miocene climate simulations analyzed can be found in the same Zenodo repository ( which provides compiled precipitation, evaporation, and surface temperature from the simulations targeting the E2MMIO and M2LMIO periods with varying CO2 concentrations (280, 400, 560 and 850 ppm). Synthesis of the master code for various figures in the manuscript are found in a separate Zenodo repository (

Additional Miocene Simulations that have been published since the Burls et al. (2021) & Acosta et al. (2023) synthesis papers are listed below and are available for further Miocene MIP of opportunity analysis:

A table summarizing these simulation is coming soon…

MioMIP2 (Phase 1)

As part of  the coordinated MioMIP2 Phase 1 effort, several modeling groups have begun running MCO simulations using the updated Herold boundary conditions published in Burls et al. (2021). The output from the Phase 1 simulations will be added to the DeepMIP-Miocene database and made available to the larger community following a dissemination strategy that will be outlined in the MioMIP2 experimental design paper.

MioMIP2 (Phase 2) 

Once published, the MioMIP2 experimental design paper will outline the boundary conditions and experimental protocols that modeling groups will use for the MioMIP2 Phase 2 CORE and sensitivity experiments.
