Large ensemble of downscaled historical daily snowfall from an earth system model to 5.5 km resolution over Dronning Maud Land, Antarctica
We explore a methodology to statistically downscale snowfall - the primary driver of surface mass balance in Antarctica - from an ensemble of historical (1850-present day) simulations performed with an earth system model over the coastal region of Dronning Maud Land (East Antarctica). This approach...
