WebAerosol Optical Depth. Airborne aerosols can cause or prevent cloud formation and harm human health. These maps depict aerosol concentrations in the air based on how the tiny particles reflect or absorb visible and infrared light. The depth of the planetary boundary layer ranges from as little as about 100 metres (330 ft) on clear, calm nights to 3,000 m (9,800 ft) or more during the afternoon in dry regions. The average temperature of the atmosphere at Earth's surface is 14 °C (57 °F; 287 K) or 15 °C (59 °F; 288 K), depending on the reference. See more The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most See more In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile with altitude, and may remain relatively constant or even increase with altitude in some regions (see the temperature section, … See more Solar radiation (or sunlight) is the energy Earth receives from the Sun. Earth also emits radiation back into space, but at longer wavelengths that humans cannot see. Part of the incoming and emitted radiation is absorbed or reflected by the atmosphere. In May … See more Earliest atmosphere The first atmosphere consisted of gases in the solar nebula, primarily hydrogen. There were probably simple hydrides such as those now found in the gas giants (Jupiter and Saturn), notably water vapor, methane See more The three major constituents of Earth's atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere … See more Pressure and thickness The average atmospheric pressure at sea level is defined by the International Standard Atmosphere as … See more Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is … See more

WebMay 17, 2024 · Optical depth describes the amount of light attenuated (scattered or absorbed) above Curiosity. An optical depth measurement, or tau, is defined as the logarithm of the ratio of the transmitted energy flux through some layer of the atmosphere to the received energy flux. WebThe aerosol quantity determined by most instruments is the aerosol optical depth (AOD). This is related to the amount of light aerosols scatter or absorb in a column through the …
