🧰 Description techniqueLalot et al. (2015) utilised a series of images to establish longitudinal temperature profiles of a river where it flows above an aquifer. | 📏 Accuracy / Resolution75% of the temperature differences, between in situ observations and TIR image-based estimations, remained within the ±1 ◦C interval. | ||||
