Structurally complex forests better at carbon sequestration

Forests in the eastern United States that are structurally complex—meaning the arrangement of vegetation is highly varied—sequester more carbon, according to a new study led by researchers at Virginia Commonwealth University.

Looking for freshwater in all the snowy places

Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers ...

21st century archaeology has rediscovered historical Cordoba

New lidar instruments peer skyward for clues on weather and climate

Researchers have developed a set of diode-based lidar instruments that could help fill important gaps in meteorological observations and fuel a leap in understanding, modeling and predicting weather and climate. The instruments ...

High-tech border wall plan on display at CES

The same technology used in self-driving cars is being touted as a potential high-tech solution to the US border wall conundrum—with some added benefits.

Lidar accelerates hurricane recovery in the Carolinas

Hurricane Florence's slow trot over North and South Carolina in September led to inundating rain, record storm surges, and another major disaster for the Federal Emergency Management Agency (FEMA) to contend with. Facing ...

LIDAR

LIDAR (Light Detection And Ranging, also LADAR) is an optical remote sensing technology that can measure the distance to, or other properties of a target by illuminating the target with light, often using pulses from a laser. LIDAR technology has application in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing and atmospheric physics, as well as in airborne laser swath mapping (ALSM), laser altimetry and LIDAR contour mapping.

The acronym LADAR (Laser Detection and Ranging) is often used in military contexts. The term "laser radar" is sometimes used, even though LIDAR does not employ microwaves or radio waves and therefore is not radar in the strict sense of the word.
