- Terrain Elevation | NASA Earthdata
NASA's terrain elevation data measure current height and changes in land altitude and are useful for creating digital elevation models
- What is the altitude of the International Space Station?
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
- Air Mass Density | NASA Earthdata
Dry air is referred to as air from which measurable amounts of water vapor have been physically removed Pure, dry air has a density of 1 293 kg m−3 at a temperature of 273 K and a pressure of 101 325 kPa Apart from the variability of water vapor, the composition of air is essentially constant to an altitude of at least 50 km
- Does humidity change with altitude - Answers
Altitude is primarily based on air pressure, not temperature and humidity Additional information, such as air pressure or location, would be needed to accurately determine altitude
- On the Trail of Contrails | NASA Earthdata
Contrails are the linear clouds etched across the skies by high-altitude airplanes as more than 90,000 flights per day crisscross the globe Whether natural or man-made, clouds can help warm or cool Earth: they reflect incoming sunlight and trap heat in the atmosphere
- GNSS | NASA Earthdata
In total, the Galileo constellation will consist of 30 satellites (27 operational and 3 spares) in three orbital planes at an altitude of 23,222 kilometers, while the ground segment contains control centers located in Europe, and a network of sensor stations and uplink stations installed around the globe
- Remote Sensing | NASA Earthdata
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
- Digital Elevation Terrain Model (DEM) | NASA Earthdata
A digital elevation model (DEM) is a three-dimensional graphic of the "bare earth" surface of land shown without trees, buildings or other objects
