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

The Role of Vegetation in Past and Future Global Hydroclimatic Change

Vegetation plays an important role in hydroclimate through its influence on water and energy fluxes at the land surface. Vegetation will respond in potentially competing ways to changes in temperature, precipitation, and CO2 itself, creating uncertainty in projections of future hydroclimate. Accurately simulating and projecting hydroclimate in Earth System Models (ESMs) requires that their representations of vegetation are constrained and assessed.
