Abstract:
|
Climate change research has progressed from estimating global averages to emphasizing spatial dependence and modeling spatial processes. Researchers model these processes using random functions over the terrestrial domain; common approaches utilize classical methods based on Euclidean geometry and stationarity assumptions. A more approporiate approach should utilize geodesics and basis function detrending in the spherical domain. We estimate the variogram of temperature anomaly data in degrees Celsius from the month of December 2009, demonstrate the necessity and functional form of a new variogram model, and fit our new model to the variogram estimates.
