The troposphere is the lowest layer of Earth's atmosphere. It extends from Earth's surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator, [17] with some variation due
The mesopause, at an altitude of 80–90 km (50–56 mi), separates the mesosphere from the thermosphere—the second-outermost layer of Earth's atmosphere. On Earth, the mesopause nearly co-incides with the turbopause, below which different chemical species are well-mixed due to turbulent eddies.
The atmosphere (optional simulation). The space or airborne radiometric sensor (optional simulation). It simulates any landscape as a 3D matrice of cells that contain turbid material and triangles. Turbid material is used for simulating vegetation (e.g., tree crowns, grass, agricultural crops,...) and the atmosphere.
The radiative transfer equation is a monochromatic equation to calculate radiance in a single layer of the Earth's atmosphere. To calculate the radiance for a spectral region with a finite width (e.g., to estimate the Earth's energy budget or simulate an instrument response), one has to integrate this over a band of frequencies (or wavelengths ...
The windows provide direct channels for Earth's surface to receive electromagnetic energy from the Sun, and for thermal radiation from the surface to leave to space. [3] Atmospheric windows are useful for astronomy , remote sensing , telecommunications and other science and technology applications.

Space flight occurs beyond the Earth's atmosphere, and space flight simulators feature the ability to roll, pitch, and yaw. Space flight simulators use flight dynamics in a free environment; this free environment lets the spacecraft move within the three-dimensional coordinate system or the x, y, and z (applicate) axis.
Supercomputer simulation shows that climate extremes are likely to drive land mammal extinction during an eventual supercontinent formation. That supercontinent could form within the next 250 ...
