Data: A reconstruction of global hydroclimate and dynamical variables over the Common Era

The Paleo Hydrodynamics Data Assimilation product (PHYDA) is 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 NOAA NCEI data pages and through th

Congrats to Arianna Varuolo-Clarke!

PaleoDynamics lab member, Arianna Varuolo-Clarke, has successfully passed her oral qualifying exam in the Department of Earth and Environmental Sciences.  Ari passed with flying colors and presented her qualifying paper titled "Diagnosing twentieth-century past and future centennial wetting trends in Southeastern South America in observations and climate model simulations."  Her work on this topic continues.  Look out for a soon to be submitted paper and her 2020 Fall AGU presentation on the topic titled "Gross di
