Combined Effects of Evaporation, Hydrogeochemical Processes, and Groundwater Flow on the Evolution of Isotopes and Trace Elements in the Badain Jaran Desert, China

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Evaporation exerts a dominant influence on groundwater‐lake interactions in arid environments, yet its coupling with redox dynamics and trace element mobilization remains poorly understood. Here, we combine stable isotope (δ2H, δ18O) and trace element concentration analyses of manganese (Mn), arsenic (As), and barium (Ba) to quantify ...

Regional Differences in the Direct and Indirect Impacts of China's Urbanization Process on Vegetation

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Urbanization profoundly influences urban vegetation dynamics. Variations in development stages lead to differing direct (vegetation loss) and indirect (vegetation growth) impacts across old urban areas, new urban areas, and suburban, with unclear spatiotemporal mechanisms.

Unravelling the spatial and temporal variability of natural disturbances in European forests

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
The heterogeneity of natural disturbance patterns and high temporal variability across European Forest suggest the need of adopting context‐dependent management strategies tailored to both the dominant disturbance agent and local environmental conditions, particularly in the most vulnerable regions, such as the Iberian Peninsula—with large and frequent

Environmental and Anthropogenic Drivers of Giraffe Occurrence and Relative Abundance in a Mixed‐Use Savannah

African Journal of Ecology, Volume 64, Issue 3, April 2026.
ABSTRACT This study examines how reticulated giraffe (Giraffa reticulata) respond to the combined effects of climate variability and human land use in a fragmented savannah system. The research was conducted in Loisaba Conservancy, Kenya, a multi‐use rangeland where wildlife coexists with pastoral livestock under increasingly variable climatic ...

Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

Boreas, Volume 55, Issue 2, Page 422-442, April 2026.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.

Landsat-8 TIRS radiometric calibration status

Earth Observing Systems XXV, 2020
The Landsat-8 Thermal Infrared Sensor (TIRS) has been acquiring two-band thermal infrared images of the Earth’s surface since 2013. The calibration of the two-band system has been monitored using the on-board calibrator and validated with vicarious calibration performed by NASA/Jet Propulsion Laboratory and Rochester Institute of Technology since ...

Landsat-8 data processing evolution

SPIE Proceedings, 2014
Shortly after Landsat-8 launched in February 2013, the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center began creating radiometrically and geometrically corrected products. In order to provide these products as soon as possible, the Landsat Product Generation System (LPGS) was developed based on instrument designs and

Landsat 8 TIRS calibration with external sensors

Earth Observing Systems XXII, 2017
This paper deals with a calibration algorithm to be used with data from the Thermal Infrared Sensor (TIRS) on board Landsat 8. Some non-uniform banding calibration errors have been observed in TIRS data since it was launched in 2013. Investigations have shown that this artifact is due to out-of-field radiance that scatters onto the TIRS focal plane.

การจำแนกการใช้ประโยชน์ที่ดินด้วยวิธีการซัพพอร์ตเวกเตอร์แมชชีนจากภาพถ่ายดาวเทียม LANDSAT 8 เพื่อประเมินปริมาณการใช้น้ำในพื้นที่จังหวัดกาฬสินธุ์

2023
งานวิจัยนี้มีจุดประสงค์เพื่อเปรียบเทียบการจำแนกการใช้ประโยชน์ที่ดินจากภาพถ่ายดาวเทียม Landsat 8 ในปี พ.ศ. 2557 และ 2559 ด้วยวิธีซัพพอร์ตเวกเตอร์แมชชีน (Support Vector Machine: SVMs) กับวิธีความน่าจะเป็นไปได้สูงสุด (Maximum Likelihood Classifier: MLC) ในพื้นที่จังหวัดกาฬสินธุ์ นำผลที่ได้จากการจำแนกมาวิเคราะห์การเปลี่ยนแปลงการใช้ประโยชน์ที่ดิน เพื่อประเมิ
