Thermal imaging is a non-contact sensing method that detects and visualizes spatial distributions of infrared radiation emitted by objects, converting them into temperature-resolved images. It typically employs uncooled microbolometer arrays or cooled photon detectors sensitive to mid- or long-wave infrared bands, with optics and calibration algorithms to map radiance to apparent surface temperature. The technique enables quantitative thermography, including emissivity correction, noise filtering, and temporal analysis, and is widely used for condition monitoring, biomedical diagnostics, materials characterization, building envelope assessment, and process control, where high sensitivity to small temperature gradients and accurate radiometric calibration are critical for reliable measurement and interpretation.
Global rainfall maps are built from observations collected by multiple satellites, but they have an important limitation. The satellites that provide these measurements cannot see the whole Earth at once. As a result, some ...

Cities trying to cool sweltering streets often set broad tree canopy targets. But those targets can overlook the reality that not all shade is equally useful, and not every neighborhood has room for more trees.
