Streamflow Spatial Correlation Length Increases During Storms and Its Application in Data Assimilation Improves Streamflow Predictions

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract The spatial correlation of streamflow in a river network captures how flows at different locations relate to one another and influence the downstream response. In this study, we analyze the spatial correlation of streamflow and rainfall during storm events in three Texas watersheds: San Antonio (2015 and 2016 storms), Guadalupe (2018 storm ...

Incorporating County‐Level Spatial Resolution in Maize Life Cycle Emissions Analysis in Illinois, USA

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
Spatial life cycle analysis (LCA) shows that the carbon intensity (CI) of maize grain used for ethanol production in Illinois, USA varies across the state, with an average carbon intensity of 14%–17% lower than the national average used in policy decisions.

Benchmarking Knowledge-assisted Kriging for Automated Spatial Interpolation of Wind Measurements

open access: yes
- We have benchmarked a novel knowledge-assisted kriging algorithm that allows regions of spatial cohesion to be specified and variograms calculated for each region.

Spatial Variation of Acidic Sodic Soils in High‐Andean Environments and Theoretical Estimation of Gypsum Requirement

open access: yesSoil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT High‐Andean forage systems are characterized by extensive management of cultivated forages, primarily through rotation of forage oats (Avena sativa) and alfalfa (Medicago sativa), under marginal edaphoclimatic conditions. Within this context, soil sodicity severely constrains the productivity of these systems in the districts of Ayaviri and ...

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly

Kriging Models That Are Robust With Respect to Simulation Errors

open access: yes
In the field of the Design and Analysis of Computer Experiments (DACE) meta-models are used to approximate time-consuming simulations. These simulations often contain simulation-model errors in the output variables.

Aggregation of ecological indicators for mapping aquatic nature quality : overview of existing methods and case studies

open access: yes, 2010
Indicators for aquatic nature quality are calculated using ecological monitoring data from individual sampling stations. For reporting purposes, these results need to be aggregated and scaled up to higher levels (catchment area, country).
