Interpolation of ionospheric modalities using kriging, co-kriging and spatio-temporal kriging
, 2018 Long distance communication and navigation systems operating in the HF band use interacting signals as they travel through the ionosphere. It is important to accurately model ionospheric behavior to increase the performance of these systems. Delays occurring in the signals depend on the refrectivity which is a function of frequency of the signals, and ...

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends
International Journal of Climatology, Volume 46, Issue 6, May 2026.Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.Abstract Marine mammals can exhibit high plasticity in foraging strategies, but how such plasticity is driven by environmental conditions is poorly understood. The American manatee (Trichechus manatus), a large, endangered herbivore, inhabits marine, estuarine, and freshwater environments.

Journal of Philanthropy, Volume 31, Issue 2, May 2026.ABSTRACT Addressing ongoing calls for a more robust understanding of philanthropic foundations, this paper uses metaphor analysis to map and analyse analogical metaphors on foundations—metaphors that make a direct comparison between philanthropic foundations and another domain—put forward in academic and non‐academic discourse.

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.Abstract Continental shelf sediments play a key role in the global carbon cycle through the long‐term storage of organic carbon (OC). However, outside of a few continental shelves dominated by large rivers our understanding of the mechanisms that drive the remineralization, burial and storage of OC across these sedimentary systems is underdeveloped.

Appraisal of the geostatistical methods to estimate Mazandaran coastal ground water quality
Caspian Journal of Environmental Sciences, 2014 The present study was carried out to evaluate three interpolation methods including weighted moving average (WMA) with the power of 2 and 3, Kriging and Cokriging methods.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.Abstract Quantifying decadal‐scale erosion rates in tectonically active regions is essential for assessing landscape hazards and constraining sediment budgets. A key question in Earth surface processes is how contemporary erosion measurements influenced by recent climatic extremes relate to long‐term geological rates.
