GPS by Paul E. Ceruzzi Explains the Entire Story

The roots of GPS extend further back in time than the 1960’s and 70’s. Having accurate clocks and using objects in the sky to navigate are hundreds of years old. If you are in the geomatics business and like to … 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
