Researchers give radar new abilities using optical data about meteors — ScienceDaily

It is thought that over 1,000 kilograms of so-called interplanetary dust falls to Earth every day. This dust is essentially an untold number of small faint meteors, discarded remnants of asteroids and comets that pass by the Earth. Two ways to study faint meteors are radar and optical observations, each with advantages and limitations. Astronomers […]

Copernicus Sentinel-6 measuring sea-levels using radar altimetry

Credit: CC0 Public Domain This November the newest member of the EU’s Copernicus program, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA’s former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed. The mission […]

Radar Observations of a Tornado Associated with Typhoon Hagibis

Tropical cyclones not only bring strong winds and heavy rains but can also generate tornadoes. Even though tropical cyclone‐tornados occur relatively frequently, worldwide documentation is sparse and studies have been limited. Put simply, the processes of tornado formation, or “tornadogenesis”, for tropical cyclone‐tornados is not well understood, especially in comparison to more frequently […]
