Accounting for Geometric Anisotropy in Sparse Magnetic Data Using a Modified Interpolation Algorithm

open access: yesRemote Sensing
The construction of a high-precision geomagnetic map is a prerequisite for geomagnetic navigation and magnetic target-detection technology. The Kriging interpolation algorithm makes use of the variogram to perform linear unbiased and optimal estimation ...

Selection of a semivariogram model in the study of spatial distribution of soil moisture

open access: yesJournal of Water and Land Development, 2017
The paper presents a selection of a semivariogram model in the study of spatial variability of soil moisture in a loess agricultural catchment. Soil moisture tests were carried out in the Moszenki village, 15 km northwest of Lublin.

Kriging algorithm for mapping the gravimetric data in the north of Algeria

open access: yesGeodetski Vestnik
The purpose of this work is to analyze and validate the gravimetric information in the study area in order to highlight the valid data for mapping the gravity anomaly from a grid generated by interpolation. In this context, we have performed a first step

Mathematical aspects of the kriging applied on landslide in Halenkovice (Czech Republic)

open access: yesOpen Geosciences, 2016
Kriging is one of the geostatistical techniques for spatial data analysis that is usually used for a modelling of natural phenomena or a creation of digital elevation models.

How Variable Are Cold Pools?

open access: yesGeophysical Research Letters
Cold pools formed by precipitating convective clouds are an important source of mesoscale temperature variability. However, their sub‐mesoscale (100 m–10 km) structure has not been quantified, impeding validation of numerical models and understanding of ...

Geostatistical interpretation of paleoceanographic data over large ocean basins - Reality and fiction [PDF]

open access: yes, 1998
A promising approach to reconstruct oceanographic scenarios of past time slices is to drive numerical ocean circulation models with sea surface temperatures, salinities, and ice distributions derived from sediment core data.

Properties of the intrinsically stationary stochastic processes

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2017
Intrinsically stationary random processes with continuous time are investigated. Their connections with second-order stationary processes and processes with the second-order stationary increments are studied.
