Bio-indicator Lidar

A research scientist at NASA Goddard has developed a lidar-based sensor technology that can detect organic compounds which would be an indicator of life as we know it, now or in the past. Once on another planet, the device, which … Continue reading

Multi-Wavelength DIAL

A team of researchers in China have demonstrated an increase in accuracy when using a multi-wavelength differential absorption lidar to measure carbon dioxide as compared to the standard dual wavelength. They note: Differential absorption LIDAR (DIAL) remote sensing is a … Continue reading

Lidar Could Detect Clear – Air Turbulence

From this article in Popular Mechanics they explain, “These days, airlines and air traffic controllers are very, very good at routing planes around the clouds and thunderstorms that bring heavy turbulence, because these weather events show up in neon colors … Continue reading

Separating Lidar Signal from Sunlight

This research paper begins with the premise that sunlight contamination dominates the backscatter noise in space-based lidar measurements during the daytime. The background scattered sunlight is highly variable and dependent upon the surface and atmospheric albedo. The scattered sunlight contribution … Continue reading

Using Spaceborne Lidar to Improve Climate Models

From this paper by two Korean researchers: “Canopy height is closely related to biomass and aerodynamic properties, which regulate turbulent transfer of energy and mass at the soil-vegetation-atmosphere continuum. However, this key information has been prescribed as a constant value … Continue reading
