Russian scientists have compared the effectiveness of several techniques of remote water temperature detection based on laser spectroscopy and evaluated various approaches to spectral profile interpretation. The paper detailing the study was published in Optics Letters. The researchers examined four data processing techniques drawing on the relevant analyses in prior publications. The technique that the authors themselves previously developed was precise up to 0.15 degrees Celsius. The research findings will support further development of sea surface temperature remote sensing solutions, enabling scientists to keep track of thermal energy flows in hard-to-reach areas such as the Arctic region, where average temperatures are rising approximately twice as fast as they are elsewhere on the planet.
