- 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
- 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
- On what date does sun appear to be at its highest altitude at . . . - Answers
The altitude of the sun is the angle between the sun and the observer's horizontal plane It changes throughout the day as the sun rises and sets At solar noon, when the sun is at its highest
- 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
- 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
- The Precision Behind Sea Level Rise | NASA Earthdata
Sea level change, and the rate of this change, is derived from calculations of sea surface height By averaging the hundreds of thousands of satellite-collected altimetry measurements acquired over the same orbital track by TOPEX Poseidon, the Jason series of satellites, and, now, Sentinel-6 Michael Freilich, global mean sea level can be determined with a precision of several millimeters along
