Thermal Infrared Sensor (TIRS) | Landsat Science

The Thermal Infrared Sensor (TIRS) measures land surface temperature in two thermal bands with a new technology that applies quantum physics to detect heat. TIRS was added to the satellite mission when it became clear that state water resource managers rely on the highly accurate measurements of Earth’s thermal energy obtained by Landsat 8’s predecessors, Landsat 5 and Landsat 7, to track ...

Thermal infrared remote-sensing detection of thermal ...

· Remote-sensed thermal infrared (TIR) images have been used to detect thermal anomaly areas (most of them are geothermal) for many years, which offer the advantages of ease of repetition, high spatial resolution, short temporal sampling intervals, and wide area coverage (Allis et al., 1999, Lee, 1978, Lagios et al., 2007, Coolbaugh et al., 2007).

Lightweight U-Net for cloud detection of visible and ...

· In this paper, a lightweight deep learning network for cloud detection of visible and thermal infrared remote sensing images is proposed. Depthwise separable convolutions is applied to compress the model of U-Net and accelerate the inference speed of the neural network. The proposed method is verified on Landsat 8 remote sensing images. Experimental results show that the proposed method can efficiently detect clouds on visible and thermal infrared …

Thermal Infrared Images and their Applications

Thermal infrared remote sensing has been recognized for a long time one of the most feasible means to detect and evaluate water stress and to quantify evapotranspiration over large areas and in a spatially distributed manner. Water stress is considered to be a major environmental factor limiting plant productivity world-wide. Water stress develops in plants as evaporative losses cannot be ...

Thermal Imaging -

Many multispectral (MSS) systems sense radiation in the thermal infrared as well as the visible and reflected infrared portions of the spectrum. However, remote sensing of energy emitted from the Earth's surface in the thermal infrared (3 μm to 15 μm) is different than the sensing of reflected energy. Thermal sensors use photo detectors sensitive to the direct contact of photons on their ...

CHAPTER 8: Thermal Infrared Remote Sensing

Thermal Infrared Remote Sensing Thermal infrared energy is emitted from all objects that have a temperature greater than absolute zero. Therefore, all the features we encounter in the landscape on a typical day (Sun, vegetation, soil, rocks, water, and even people) emit thermal infrared electromagnetic radiation. Humans eyes cannot detect differences in thermal infrared
