Determination of Optimum Viewing Angles for the Angular Normalization of Land Surface Temperature over Vegetated Surface

Sensors, 2015
Multi-angular observation of land surface thermal radiation is considered to be a promising method of performing the angular normalization of land surface temperature (LST) retrieved from remote sensing data. This paper focuses on an investigation of the

Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Resolving the Physical Ambiguity of Passive Infrared Cloud Optical Thickness Retrievals With Microwave Observations

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite thermal infrared (TIR) observations, combined with machine‐learning methods, enable nighttime retrievals of cloud optical thickness (COT), but their cloud‐top‐dominated radiances provide ambiguous information for optically thick clouds.

Sky‐Directional Radiative Cooling Meta‐Films for Daylighting Windows

Advanced Functional Materials, Volume 36, Issue 76, 21 September 2026.
A geometry‐mediated microprism meta‐film enables transparent, sky‐directional radiative cooling for daylighting windows. By decoupling control of visible transmittance from mid‐infrared emissivity, ground‐emitted heat absorption is suppressed while skyward heat dissipation is enhanced.

Identifying Upflow Zone Based on Thermal Infrared (TIR) Sensor and Field Measurements at Volcanic Field

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Upflow zone identification at volcanic fields is crucial for geothermal resource exploration. The common problem to identify the upflow zone using conventional mapping method is time-consuming and the limitation of access to the area.

Thermal Infrared Ground Based Instruments: Lessons Learned (PPT)

, 2020
With the imminent launch of the JWST, the field of thermal-infrared (TIR) astronomy will enjoy a revolution. It is easy to imagine that all areas of infrared (IR) astronomy will be greatly advanced, but perhaps impossible to conceive of the new vistas ...

Influence of Micro‐Scale Surface Texturing on Light Distribution From Luminescent Downshifting Layers for Next‐Generation Greenhouses

Global Challenges, Volume 10, Issue 9, September 2026.
This work investigates two different luminophores that convert ultraviolet to red light along with a wide range of microstructures to maximise outcoupling of the luminescence as well as the incoming solar radiation onto the greenhouse floor. Starting with small‐area (25 cm2) luminescent down‐shifting (LDS) layers, the best designs are then evaluated ...
