Optical science supplies answers to questions related to changes in the environment and provides a mechanism to chart improvements into the future.MARIE FREEBODY, CONTRIBUTING EDITORAs temperatures and carbon dioxide concentrations rise to levels not previously recorded, shifts in weather and other environmental changes are impacting the global landscape. With the U.N. recording one climate-related crisis every week in 2019, such as the forest fires in the U.S. and bushfires in Australia, the consequences of such a globally disrupted climate are many and difficult to track. This is so because of variables such as altitude, movement, and the size of equipment used to measure these phenomena. The near-infrared band from the multispectral instrument (MSI) of...Read full articleRelated content from Photonics MediaARTICLESGas Mapping LiDAR Quantifies Methane EmissionsSouthern California Gas Co.
