Study on thermal infrared emission directionality over crop canopies with TIR camera imagery

Science in China Series E: Technological Sciences, 2000
In order to investigate directionality of thermal infrared emission from crop canopies, a wide-angle thermal video camera (INFRAMETRICS) equipped with an 80° FOV lens was mounted on a small aircraft and used to acquire thermal imagery along several different flight traces.

Dual‐Band Modulation of Emissivity and Solar Transmittance Through Chemical Composition‐Tuned Asymmetric Layer‐by‐Layer Assembly

Advanced Science, EarlyView.
An unconventional asymmetric Layer‐by‐Layer (LbL) assembly technique was developed to fabricate a Fabry‐Pérot (F‐P) resonator, which enhances luminous transmittance (Tlum) and enables dual‐band modulation in both the near‐infrared (NIR) and mid‐infrared (MIR) regions.

Diurnal Air–Surface Temperature Dynamics in Hong Kong: An Analysis Across Land Use and Climate Zones

International Journal of Climatology, EarlyView.
Daytime and nighttime air temperature (Ta) from automatic weather stations and land surface temperature (Ts) derived from ASTER and Landsat 8–9 are used to examine the relationship between Ta and Ts. The spatial and statistical characteristics of Ta − Ts dynamics are further analysed across land use (LU) and local climate zones (LCZ).

PHOTOGRAMMETRIC 3D BUILDING RECONSTRUCTION FROM THERMAL IMAGES [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
This paper addresses the problem of 3D building reconstruction from thermal infrared (TIR) images. We show that a commercial Computer Vision software can be used to automatically orient sequences of TIR images taken from an Unmanned Aerial Vehicle (UAV)

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

River Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

THERMAL IR IMAGING: IMAGE QUALITY AND ORTHOPHOTO GENERATION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
This paper deals with two aspects of photogrammetric processing of thermal images: image quality and 3D reconstruction quality. The first aspect of the paper relates to the influence of day light on Thermal InfraRed (TIR) images captured by an Unmanned ...

Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

Wildlife Biology, EarlyView.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.

Characteristics of Intense Multi‐Day Wet Spells Over West Africa

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
The study reveals a significant increase in intense wet spells, particularly in KASS‐D, emphasising the value of dense rain‐gauge networks. Larger‐sized events have grown, while smaller ones declined, boosting 3‐day and 5‐day wet spells' contribution to annual rainfall, with the Guinea Coast showing the highest increase and the Sahel the lowest ...

A cross-comparison of thermal infrared versus ultraviolet ground-based retrievals of SO2 masses during Strombolian explosions

Volcanica
This study investigates sulfur dioxide (SO2) emissions from Stromboli’s explosive activity using ground-based remote sensing techniques. We analyze the SO2 mass derived from ultraviolet (UV) and thermal infrared (TIR) cameras, alongside explosion ...
