Interpolation of ionospheric modalities using kriging, co-kriging and spatio-temporal kriging

, 2018
Long distance communication and navigation systems operating in the HF band use interacting signals as they travel through the ionosphere. It is important to accurately model ionospheric behavior to increase the performance of these systems. Delays occurring in the signals depend on the refrectivity which is a function of frequency of the signals, and ...

PVM Kriging with R

, 2003
Kriging is one of the most frequently used prediction methods in spatial data analysis. This paper examines which steps of the underlying algorithms can be performed in parallel on a PVM cluster. It will be shown, that some properties of the so called

Disjunctive kriging for environmental management

, 1996
Land managers, legislators and law enforcement agencies must often make decisions based on critical thresholds and using estimates that are subject to error. Disjunctive kriging enables this error to be converted to an estimated probability that the true
