The Paleo Hydrodynamics Data Assimilation product has been published in Scientific Data

May 22, 2018

Nathan Steiger and co-authors have published the Paleo Hydrodynamics Data Assimilation product (PHYDA) in the Nature journal Scientific Data.  The paper describes the development of the PHYDA and validates the reconstructions that it contains against observational data and other paleoclimatic reconstructions.  The work is significant as the first global reconstruction of hydroclimate and associated dynamical variables.  It uses a novel data assimilation method and the largest multiproxy database assembled to date by combining several community-complied proxy datasets.  The reconstructions, code, and proxy data were all made public upon publication and are available through the links provided in the publication, through our PHYDA data page, or through the NOAA NCEI data pages.
