Journal of Metamorphic Geology, EarlyView.ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

Generalized product-sum variogram models of the data of the Center of Marine Research
Lietuvos Matematikos Rinkinys, 2004 Environmental data usually depends on both spatial and temporal components. Therefore, it is essential to have statistical models to describe how the data vary across space and time.

Validating habitat suitability assessments with post‐translocation animal movement data
Restoration Ecology, EarlyView.Wildlife translocations are essential for restoring species to their native habitats, and species distribution models (SDMs) have proven useful for identifying suitable habitats to guide this process. Validating model predictions with data from individual's post‐translocation, however, is rare due to the frequent lack of monitoring data from ...

Optimal designs for variogram estimation
Environmetrics, 1999 The variogram plays a central role in the analysis of geostatistical data. A valid variogram model is selected and the parameters of that model are estimated before kriging (spatial prediction) is performed. These inference procedures are generally based upon examination of the empirical variogram, which consists of average squared differences of data ...

Generalized Additive Model With Dynamic Coefficients for Spatiotemporal Ozone Predictions
Environmetrics, Volume 37, Issue 3, April 2026.ABSTRACT Accurate prediction of surface‐level ozone concentrations is critical for air quality management and public health protection. This study develops a flexible spatiotemporal statistical modeling framework to predict daily mean O3 concentrations across Italy by integrating satellite‐derived ozone estimates with ground‐based observations and high‐

GloMarGridding: A Python Toolkit for Flexible Spatial Interpolation in Climate Applications
Geoscience Data Journal, Volume 13, Issue 2, April 2026.Global surface climate datasets contain structural uncertainty that is difficult to attribute to individual processing steps. We present GloMarGridding, a Python package that isolates the spatial interpolation component using Gaussian Process Regression (or kriging) to generate spatially complete fields and uncertainty estimates. The techniques used in

Spanish Journal of Agricultural Research, 2014 Knowledge of infiltration characteristics is useful in hydrological studies of agricultural soils. Soil hydraulic parameters such as steady infiltration rate, sorptivity, and transmissivity can exhibit appreciable spatial variability. The main objectives
