Altitude - Earthdata
网页2020年9月18日 · Altitude. A measure of height, especially of great height, as a mountain top or aircraft flight level. In meteorology, altitude is used almost exclusively with respect to the height of an airborne object above the earth's surface, above a constant pressure surface, or above mean sea level. Definition source: American Meteorological Society.
Contrails - Earthdata
网页Contrails are human-induced clouds that usually form at very high altitudes (usually above 8 km - about 26,000 ft) where the air is extremely cold (less than -40ºC). Because of this, contrails form not when an airplane is taking off or landing, but while it is at cruise altitude. (Exceptions occur in places like Alaska and Canada, where very cold air is sometimes …
CALIOP | Earthdata
网页2006年4月28日 · The Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) is a two-wavelength lidar that provides high-resolution vertical profiles of aerosols and clouds. CALIOP is one of three instruments aboard the joint NASA/French Space Agency Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite, which …
On the Trail of Contrails - Earthdata
网页2013年10月11日 · On top of that, most commercial jets cruise at 26,000 feet or higher, where temperatures are cold enough that the large volumes of condensed vapor instantly freeze and form visible contrail clouds. Spangenberg said, “That’s why contrails form at the high altitudes where the jet liners fly.
Dropping in on a Hurricane | Earthdata
网页2002年2月22日 · Based at the Naval Air Station in Jacksonville, Florida, the CAMEX-4 team embarked on a campaign to study hurricane development, tracking, and landfall impacts. The researchers hoped to gather valuable hurricane data by venturing into a hurricane at high altitudes, but there was just one problem: a shortage of hurricanes in the Atlantic.
网页form at the high altitudes where the jet lin-ers fly. Lower altitude aircraft are not going to create them because the temperature is not low enough.” In very humid conditions, some aircraft may also produce wingtip vortices, or contrails that spiral out behind each wing. Low-flying planes at airshows often generate what look like

It provides end-to-end capabilities for managing NASA’s Earth science data from various sources—satellites, aircraft, field measurements, and various other programs.
Dr. David Peterson | Earthdata
网页2023年8月28日 · Among the scientists interested in pyrocumulonimbus clouds and their ability to bring smoke to such lofty heights is Dr. David Peterson, a meteorologist with the Naval Research Laboratory’s ( NRL) Marine Meteorology Division in Monterey, California. Peterson and his colleagues use satellite data and global aerosol models to monitor and …

Cloud to Cloud: Forecasting Storm Severity with Lightning
网页2006年2月13日 · This pattern of lightning activity often even preceded the occurrence of cloud-to-ground lightning strikes by several minutes--information forecasters could use to issue earlier warnings to communities and airports in a storm's path. Lightning illuminates a funnel cloud forming during a storm near Huntsville, Alabama, in April 2006. Alabama's ...
