About
Dr. Schneider earned graduate degrees in Atmospheric, Oceanic and Space Sciences from the University of Michigan and received postdoctoral training in Earth System Science from the University of California, Irvine. His research has involved development of snow radiative transfer models and an instrument designed to infer snow grain size from bidirectional reflectance measurements. He also designed the firn layering implementation and density parameterization in the United States Department of Energy (DOE) Energy Exascale Earth System Model and has conducted evaluations of cryosphere-climate processes in Earth system models and in reanalysis data sets. He currently works on production and evaluation of a coupled Unified Forecast System reanalysis and initial conditions for "reforecasts," which enable diagnostic verification and model calibration.
