, 2018 We consider the problem of describing excursion sets of a real-valued function $f$, i.e. the set of inputs where $f$ is above a fixed threshold. Such regions are hard to visualize if the input space dimension, $d$, is higher than 2.

Sparse polynomial chaos expansion for universal stochastic kriging
Journal of Computational and Applied MathematicsSurrogate modelling techniques have opened up new possibilities to overcome the limitations of computationally intensive numerical models in various areas of engineering and science. However, while fundamental in many engineering applications and decision-making, the incorporation of uncertainty quantification into meta-models remains a challenging ...

A Step Toward Rainfall Erosivity Mapping Over Türkiye Using Kriging With External Drift
Hydrological Processes, Volume 40, Issue 3, March 2026.This study maps rainfall erosivity (R factor) across Türkiye by integrating station‐based observations with satellite‐based precipitation data. The Modified Fournier Index (MFI) derived from CHIRPS was first validated against ground measurements and subsequently incorporated as auxiliary information within a kriging with external drift (KED) framework.

Cyclone‐induced mixing and stratification shape autumnal hypoxia in a temperate estuary
Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.Abstract Autumnal hypoxia in temperate estuaries is often overlooked due to its smaller extent, weaker intensity, and sparse observations compared to summer. However, climate variability may alter its seasonality. Using 40 yr (1984–2023) of hypoxic volume data from the Chesapeake Bay, combined with numerical simulations, we examined interannual drivers

Meteorological Applications, Volume 33, Issue 2, March/April 2026.This paper presents a comprehensive methodology for evaluating the ability of satellite and reanalysis rainfall data to provide localised, historical rainfall information for agricultural applications. This meets a major need for location‐specific rainfall information to improve climate information services for millions of small‐holder farming ...

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Irrigation is essential for stabilizing yields and sustaining food production, yet it faces increasing challenges, especially in water‐scarce regions. Cosmic‐ray neutron sensors (CRNS) are a promising tool in irrigation management as they can continuously monitor soil water content (SWC) over large areas.

Geostatistical Reconstruction of Atmospheric Refractivity Fields Using Universal Kriging
GeomaticsAtmospheric refractivity governs the propagation behavior of electromagnetic waves in the lower troposphere. Accurate spatial characterization of this parameter is essential for optimizing communication, radar, and navigation systems. This study presents
