The OCO‐2 and OCO‐3 ACOS Version 11 XCO2 Data Products: A Benchmark Record for Space‐Based Global Carbon Cycle Research

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract NASA's Orbiting Carbon Observatory‐2 (OCO‐2) and OCO‐3 have been observing Earth's atmosphere from space since September 2014 and August 2019, respectively. The version 11 (v11) Atmospheric Carbon Observations from Space (ACOS) Level 2 full physics (L2FP) retrieval algorithm has been used to provide estimates of the column‐averaged dry‐air ...

TEMPO Applications During Poor Wintertime Air Quality in Salt Lake City: An Analysis of Persistent Cold Air Pooling Events

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract During the wintertime, the Salt Lake Valley (SLV) experiences episodes of poor air quality during persistent cold air pools (PCAPs), wherein the atmospheric boundary layer remains stable for several days. We examine insights into the accumulation of primary emissions during PCAPs gained from NO2 tropospheric column abundances derived from ...

Comparison of Direction of Arrival (DOA) Estimation Techniques for Closely Spaced Targets [PDF]

open access: yesInternational Journal of Future Computer and Communication, 2013
This paper deals with different beamforming techniques for DOA estimation. High resolution techniques such as Multiple Signal Classification (MUSIC) and Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) which are subspace based techniques are also discussed. Finally, further resolution improvement is achieved through the use

Harnessing Spatial and Multi‐Criteria Decision Analysis (MCDA) to Optimize Land Suitability for Kenaf Cultivation in Kelantan: Pathways for Sustainable Economic Development

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 11438-11458, September 2026.
ABSTRACT In Kelantan, entrenched land degradation and extensive idling of agricultural lands exacerbate rural poverty. Current top‐down planning often overlooks local geographic and social constraints, despite state initiatives to convert idle lands and strengthen rural livelihoods.

A Review on Heat Stress in Broiler Chickens: Mechanisms, Effects and Mitigation Strategies

open access: yesVeterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Heat stress caused by high temperature and humidity compromises broiler health, welfare, and productivity by reducing feed intake, growth performance, and feed efficiency, while increasing mortality, oxidative stress, metabolic disturbances, intestinal dysfunction, gut dysbiosis, immune suppression, and meat quality deterioration.

Adaptive Based Beamforming for Direction-of- Arrival (DOA) Estimation

open access: yesCVR Journal of Science & Technology, 2015
Nowadays mobile users require increased coverage, quality of service and capacity in wireless communications. By using adaptive antennas at both transmitter and receiver in wireless communication, we can easily reach the required improvement. In this paper Adaptive Antenna plays a major role to improve the performance of wireless communication systems.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, Volume 2026, Issue 5, September 2026.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Inside the Fire Plume Chemical Interactions: A Review on Key Processes and Future Directions

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Fire plumes are rising columns of heated air masses, consisting of gaseous and particulate matter generated by combustion, affecting air quality, climate and public health. The chemical species released undergo secondary reactions and participate in chemical and physical interactions, altering the properties of the fire plume.
