2025年1月30日 · 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 …

6 天之前 · Are found in high altitudes. May flow downwards from cirques, ice caps, highland ice fields, or ice sheets. Are shaped like long tongues of ice. Bering and Hubbard Glaciers are valley glaciers and are the longest in the Americas (200 and 150 kilometers long). Tidewater Glaciers. Are valley glaciers that enter the sea.

2025年2月6日 · Generally, the wind speeds and directions at various levels in the atmosphere above the domain of surface weather observations, as determined by any of the methods of winds-aloft observation. Definition source: National Oceanic and Atmospheric Administration

2023年10月5日 · ICESat (operational 2003 to 2010 with data available from 2003 to 2009) was the first in a series of planned missions to measure changes in ice sheet elevation and the heights of clouds and aerosols.

2021年4月19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.

2020年12月28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.

1992年1月1日 · GNSS is a space geodesy technique that provides autonomous geospatial positioning with global coverage. NASA hosts one of six global GNSS data archive centers.

2023年8月28日 · Higher UVAI values mean there is a very thick smoke plume at high altitudes. The UVAI product also helps us follow where the pyroCb smoke plume is going over time. So, we can get a sense of its dimensions and how much area it covers, and then if you bring in data from the OMPS Limb Profiler and lidar you can get a sense of the plume’s ...

NASA’s OpenAltimetry is a free and powerful map-based data visualization and discovery tool for exploring surface elevation profiles from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and ICESat platform mission altimetry data.

2025年1月29日 · Moreover, data collected from geostationary satellites can only classify wind heights as low, middle, and high, rather than at precise altitudes. A new instrument and remote sensing technique, however, may improve the accuracy of cloud motion and height data over many areas of the Earth, boosting the accuracy of weather predictions.
