- 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
- Shuttle Radar Topography Mission (SRTM) | NASA Earthdata
The Shuttle Radar Topography Mission (SRTM) payload flew aboard the Space Shuttle Endeavour during the STS-99 mission SRTM collected topographic data over nearly 80% of Earth's land surfaces, creating the first-ever near-global dataset of land elevations
- What is the altitude of Austin? - Answers
Density altitude is a measure of air density relative to standard atmospheric conditions, and it is calculated by adjusting the pressure altitude for temperature and humidity
- OpenAltimetry | NASA Earthdata
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 With OpenAltimetry, users can explore how different types of surface heights have changed across Earth over time Please note that OpenAltimetry processes
- Digital Elevation Terrain Model (DEM) | NASA Earthdata
NASA's data for digital elevation models (DEM) comes from airborne and space-based sources and are useful for analyzing a majority of Earth's terrain
- On the Trail of Contrails | NASA Earthdata
Lower altitude aircraft are not going to create them because the temperature is not low enough ” In very humid conditions, some aircraft may also produce wingtip vortices, or contrails that spiral out behind each wing Low-flying planes at airshows often generate what look like contrails, but are simply special effects created by smoke
- What is the temperature 20000 feet altitude? - Answers
As altitude increases, the temperature of air generally decreases at a rate of about 5 4°F per 1000 feet This is known as the lapse rate, and it occurs due to the decrease in air pressure with
- How high would you need to be in order to see the curvature of the . . .
To see the curvature of the Earth, you would need to be at an altitude of at least 35,000 feet, which is roughly the cruising altitude of commercial airplanes
