Atmospheric sounding

An atmospheric sounding is a measurement of vertical distribution of physical properties of the atmospheric column such as pressure, temperature, wind speed and wind direction (thus deriving wind shear), liquid water content, ozone concentration, pollution, and other properties. An atmosphere (from Greek ατμός - atmos, " Vapor " + σφαίρα - sphaira, " Sphere " Temperature is a physical property of a system that underlies the common notions of hot and cold something that is hotter generally has the greater temperature Wind speed is the Speed of Wind, the movement of air or other gases in an atmosphere Wind direction is the direction from which the Wind is blowing Wind shear, sometimes referred to as windshear or Wind gradient, is a difference in Wind speed and direction over a relatively OZONE is an object oriented Operating system written in the C programming language. Such measurements are performed in a variety of ways including remote sensing and in situ observations. Remote sensing is the small or large-scale acquisition of information of an object or phenomenon by the use of either recording or real-time sensing device(s that is not in physical In situ (ɪn siːˈtuː is a Latin phrase meaning in the place.

The most common in situ sounding is a radiosonde, which usually is a weather balloon, but can also be a rocketsonde. A radiosonde ( Sonde is French for Probe) is a unit for use in Weather balloons that measures various atmospheric parameters A weather or sounding balloon is a Balloon (specifically a type of High altitude balloon) which carries instruments aloft to send back information A rocketsonde, a kind of Sounding rocket, is a system for atmospheric observations that consists of a Rocket that launches instruments that can make

Remote sensing soundings generally use passive infrared and microwave radiometers:

airborne instruments
surface stations
Earth-observing satellite instruments such as AIRS and AMSU

There is even a sounder at Mars: the Mars climate sounder on the Mars Reconnaissance Orbiter. Infrared ( IR) radiation is Electromagnetic radiation whose Wavelength is longer than that of Visible light, but shorter than that of Microwaves are electromagnetic waves with Wavelengths ranging from 1 mm to 1 m or frequencies between 0 A radiometer is a device for measuring the radiant flux (power of Electromagnetic radiation. The Atmospheric Infrared Sounder (AIRS is an instrument on the Earth Observing System Aqua satellite launched in May 2002 The Mars climate sounder is a major instrument on the Mars Reconnaissance Orbiter. NASA 's Mars Reconnaissance Orbiter ( MRO) is a multipurpose Spacecraft designed to conduct Reconnaissance and exploration of Mars
