Abstract:
|
Predicting the future behavior of the West Antarctic ice sheet (WAIS) involves the use of computer models of ice sheet dynamics as well as ice sheet observational data. The observations are in the form of both modern satellite data and paleoclimate reconstructions. It is challenging to develop statistical methods for such data because both the data and the computer model output are in the form of binary spatial fields. I will describe an approach that combines Gaussian processes, generalized linear models, and dimension-reduction approaches for spatial data. Our results show that our methods result in sharp projections about the future state of WAIS.
