2025年3月14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 above mean sea level. Definition source: American Meteorological Society

2025年1月5日 · 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 ...

2023年8月11日 · Humidity is not directly affected by altitude. However, humidity is affected by air density and temperature. At high altitudes, the air is usually much thinner (lower pressure) and often the ...

2025年3月27日 · A digital elevation model (DEM) is a three-dimensional graphic of the "bare earth" surface of land shown without trees, buildings or other objects.

Platforms orbiting at 35,786 km are at an altitude at which their orbital speed matches the planet's rotation, and are in what is called geosynchronous orbit (GSO). In addition, a platform in GSO directly over the equator will have a geostationary orbit.

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.

2000年2月11日 · Used to gather topographic (elevation) data of Earth's surface, NASA's SRTM used interferometry.

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 ...
