Detailed mapping of soil texture of a paddy growing soil using multivariate geostatistical approaches

open access: yesTropical Agricultural Research, 2018
This study was conducted to explore performances of multivariate geostatistical techniques, co-kriging and regression kriging in contrast to univariate ordinary kriging, to generate detailed maps of soil texture by using proximally sensed apparent ...

Bootstrap based uncertainty bands for prediction in functional kriging [PDF]

open access: yes, 2016
The increasing interest in spatially correlated functional data has led to the development of appropriate geostatistical techniques that allow to predict a curve at an unmonitored location using a functional kriging with external drift model that takes ...

Evaluation of modelling approaches for predicting the spatial distribution of soil organic carbon stocks at the national scale [PDF]

open access: yes, 2014
Soil organic carbon (SOC) plays a major role in the global carbon budget. It can act as a source or a sink of atmospheric carbon, thereby possibly influencing the course of climate change.

Comparison of sensitivity of interpolation methods by rain gauge network density [PDF]

open access: yesعلوم و مهندسی آبیاری
Different interpolation methods, each with their own strengths and weaknesses, are used to temporal and spatial estimation of precipitation. The accuracy of this estimate depends on the density of point data measured at rain gauge stations. In this study,

A comparison of statistical and machine learning methods for creating national daily maps of ambient PM$_{2.5}$ concentration [PDF]

open access: yes, 2019
A typical problem in air pollution epidemiology is exposure assessment for individuals for which health data are available. Due to the sparsity of monitoring sites and the limited temporal frequency with which measurements of air pollutants ...

Ege Bölgesi’nde yağışın mekânsal dağılımı

open access: yesCoğrafi Bilimler Dergisi, 2013
Spatial modelling of climatological variables is one of the most crucial parts of environmental studies. Prediction of natural events such as hydrological phenomenon, drought, flood, ground-surface water amount, pollution of water sources, and issues ...

Metamodel-Assisted Multidisciplinary Design Optimization of a Radial Compressor

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2019
Kriging is increasingly used in metamodel-assisted design optimization. For expensive simulations; however, one can afford only a few samples to build the Kriging model, which consequently lacks prediction accuracy.
