Rethinking Model Transferability: Validity Domains as a New Approach to Delineate the Limits of Bloom Date Projections. [PDF]
Glob Chang BiolAccurately predicting future phenology events in novel environmental conditions is a key challenge in modelling. Using first bloom observations of the Japanese Yoshino cherry across a temperature gradient, we calibrated process‐based and machine learning models at multiple locations and cross‐validated them to obtain the predictive performance for all ...

Synthetic TEC Mapping with Ordinary and Universal Kriging [PDF]
2007 3rd International Conference on Recent Advances in Space Technologies, 2007 Spatiotemporal variations in the ionosphere affects the HF and satellite communications and navigation systems. Total Electron Content (TEC) is an important parameter since it can be used to analyze the spatial and temporal variability of the ionosphere.
