GEDI laser ranging observations provide the missing piece - high resolution measurements of the Earth’s 3D structure. … enabling us to address urgent questions about the Earth. Global changes are fundamentally altering Earth’s tropical and temperate forests …

The Global Ecosystem Dynamics Investigation (GEDI) instrument is a full-waveform lidar installed on the International Space Station that produces detailed observations of the 3D structure of Earth’s surface. GEDI's three lasers precisely measure forest canopy height, canopy vertical structure, and surface elevation.

2016年6月14日 · Focused on tropical and temperate forests from its vantage point on the ISS (International Space Station), GEDI uses lidar to provide the first global, high-resolution observations of forest vertical structure.

The GEDI instrument is a geodetic-class, light detection and ranging (lidar) laser system comprised of 3 lasers that produce 8 parallel tracks of observations. Each laser fires 242 times per second and illuminates a 25 m spot (a footprint) …

2018年12月5日 · Focused on tropical and temperate forests from its vantage point on the International Space Station (ISS), GEDI uses lidar to provide the first global, high-resolution observations of forest vertical structure.

The Cloud-Aerosol Transport System (CATS), launched in January of 2015, is a lidar remote sensing instrument that will provide range-resolved profile measurements of atmospheric aerosols and clouds from the International Space Station (ISS). CATS is intended to operate on-orbit for at least six months, and up to three years.

CATS, a spaceborne lidar instrument that fired more laser pulses than any previous orbiting instrument has ended its operations on the International Space Station (ISS), after a successful 33-month mission to measure clouds and tiny atmospheric particles that play key roles in Earth's climate and weather.

Goddard Space Flight Center and launched to the International Space Station (ISS) on December 5, 2018. GEDI is a multi-beam waveform LiDAR (light detection and ranging) designed to measure the Earth’s global tree height and canopy density using 8 laser beam ground tracks separated by roughly 600 meters. Given the ground coverage required and ...

2019年8月14日 · The Global Ecosystems Dynamics Investigation (GEDI) Lidar, is an Earth Science remote sensing instrument aboard the International Space Station (ISS) and the Japanese Experiment Module (JEM). Its core mission is to measure the global carbon balance of Earth's forests by using a set of three solid state laser transmitters in a multibeam waveform ...

This project observes the ground elevation and forests canopy height with the complementary measurement of an imager and lidar on the International space station (ISS). The mission equipment is operated in space through the compartment where astronauts operate, which helps mitigate the launch environment compared to the standard ISS payload.
