GIS and spatial analyses

open access: yesCrimRxiv, 2018
The importance of spatial-temporal dimension(s) within environmental criminology has made the use and applications of geographic information systems (GIS) and spatial analysis rather widespread. This chapter covers some of the principles and advancements in the use of crime mapping and spatial analysis to study the spatial distribution of crime ...

Meridional Dipole in Eddy Activity Along Peruvian Coast During Eastern Pacific El Niño Events

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale oceanic eddies (O $O$(100)km) play a key role in regulating climate by affecting the transport of heat and water mass properties. However, most climate models struggle to simulate these eddies due to coarse horizontal resolution. Using a 120‐year ultra‐high‐resolution simulation with 1/10° ${}^{\circ}$ horizontal ocean resolution ...

Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

open access: yesIrrigation and Drainage, Volume 75, Issue 2, Page 815-839, April 2026.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Distribution, Formation, and Evolution of Subsurface Secondary Acoustic Ducts From Global Ocean Modeling and Observations

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Monthly mean reanalysis from assimilating global ocean circulation models spanning 27 years is used to study subsurface secondary acoustic ducts, which provide waveguides for the transmission of mid‐frequency sound. A systematic diagnosis of secondary ducts from monthly mean temperature and salinity fields characterizes their distribution and ...
