Mar 7, 2025 · 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.

Feb 11, 2000 · Used to gather topographic (elevation) data of Earth's surface, NASA's SRTM used interferometry.

Jan 5, 2025 · This altitude allows the ISS to remain in a stable orbit while still being close enough for supply missions and crew rotations. The ISS travels at a speed of about 28,000 kilometers per hour ...

Feb 27, 2025 · The height of the atmospheric layer from the Earth's surface up to an altitude of about 1 kilometer in which wind speed and direction are affected by frictional interaction with objects on the Earth's surface.

We will produce a long-term observational dataset of daily, near-global US/M temperature profiles from roughly 25-80 km altitude covering 1991 to the present. This unique and valuable new record spanning over 20 years will facilitate studies that advance our understanding of US/M processes, how those processes are affected by climate change ...

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.

The High-Altitude Wind and Rain Airborne Profiler (HIWRAP) instrument is a Doppler radar designed to measure tropospheric winds through deriving Doppler profiles from cloud and precipitation volume backscatter (Li et al. 2016).

Jun 23, 2024 · The "effective volume" of the Earth's atmosphere is about 4.2 billion cubic kilometers. This figure is the surface area of the Earth (509 million square kilometers) times the "effective thickness ...

3 days ago · A digital elevation model (DEM) is a three-dimensional graphic of the "bare earth" surface of land shown without trees, buildings or other objects.
