Query: Calibrating an ice sheet model using high-dimensional binary spatial
  data   Rapid retreat of ice in the Amundsen Sea sector of West Antarctica may cause
drastic sea level rise, posing significant risks to populations in low-lying
coastal regions. Calibration of computer models representing the behavior of
the West Antarctic Ice Sheet is key for informative projections of future sea
level rise. However, both the relevant observations and the model output are
high-dimensional binary spatial data; existing computer model calibration
methods are unable to handle such data. Here we present a novel calibration
method for computer models whose output is in the form of binary spatial data.
To mitigate the computational and inferential challenges posed by our approach,
we apply a generalized principal component based dimension reduction method. To
demonstrate the utility of our method, we calibrate the PSU3D-ICE model by
comparing the output from a 499-member perturbed-parameter ensemble with
observations from the Amundsen Sea sector of the ice sheet. Our methods help
rigorously characterize the parameter uncertainty even in the presence of
systematic data-model discrepancies and dependence in the errors. Our method
also helps inform environmental risk analyses by contributing to improved
projections of sea level rise from the ice sheets.
