Nasa has recently tested an airborne lidar system that uses three simultaneous laser pulses to detect and measure two potent greenhouse gases: carbon dioxide and water vapour
Having to endure unpleasant air turbulence on flights could be a thing of the past, thanks to long range lidar technology being developed by Boeing and the Japan Aerospace Exploration Agency
Chinese researchers have developed a Doppler lidar system that could lead to better anticipation of hurricane formation and movement, enabling earlier evacuation warnings
Fluorescence spectroscopy has been used to characterise natural organic matter (NOM) in water. Excitation-Emission maps reveal the nature and concentration of NOM in river water and can be used as a routine analysis technique in water treatment facilities.
The Norwegian Public Roads Administration (NPRA) is collaborating with three Scandinavian research groups to explore how lidar technology could be used to measure the wind conditions across the world’s longest proposed floating bridge
The ultimate instrumentation for trace gas analysis and detection in air quality monitoring as well as industrial process control would be one that can simultaneously provide a sensitive, selective, and fast, multi-gas measurement with wide dynamic range all in a compact and robust system. One of the few such promising technologies that can deliver these requirements is laser based photoacoustic spectroscopy (PAS).
Five new NASA airborne field campaigns will take to the skies starting in 2015 to investigate how long-range air pollution, warming ocean waters, and fires in Africa affect our climate
