Adaptive optics - Wikipedia

Adaptive optics was first envisioned by Horace W. Babcock in 1953, and was also considered in science fiction, as in Poul Anderson's novel Tau Zero (1970), but it did not come into common usage until advances in computer technology during the 1990s made the technique practical.. Some of the initial development work on adaptive optics was done by the US military during the Cold War and was ...

What are passive and active sensors? | NASA

· An active sensor is a radar instrument used for measuring signals transmitted by the sensor that were reflected, refracted or scattered by the Earth's surface or its atmosphere. Spaceborne active sensors have a variety of applications related to meteorology and observation of the Earth's surface and atmosphere. For example, precipitation radars measure the radar echo from rainfall to …

How to Successfully Beat Atmospheric Seeing - Sky ...

· The atmospheric seeing is always worse at low altitudes in the sky because you're looking through more air. In addition, you face more atmospheric dispersion. This is the smearing out of a celestial image into a short spectrum, with blue on top and red on the bottom. Even as high as 60° up, the far-blue component of an image appears " ( arcsecond) above the far-red component. The ...

10 Things: Planetary Atmospheres – NASA Solar System ...

· Saturn’s atmosphere—where NASA’s Cassini spacecraft ended its 13 extraordinary years of exploration of the planet—has a few unusual features. Its winds are among the fastest in the solar system, reaching speeds of 1,118 miles (1,800 kilometers) per hour. Saturn may be the only planet in our solar system with a warm polar vortex (a mass of swirling atmospheric gas around the pole) at ...

What Is A Barometer, How It Works, Where To Place It ...

· Weather stations have several sensors that measure atmospheric conditions, with a barometer being one of them. The barometer is not a recent development, though, and comes in different forms. A barometer is a meteorological instrument that measures the atmospheric pressure of air in the environment. It is a crucial part of a weather station and is primarily used in combination with other ...

What is remote sensing? - National Ocean Service

Remote sensors collect data by detecting the energy that is reflected from Earth. These sensors can be on satellites or mounted on aircraft. Remote sensors can be either passive or active. Passive sensors respond to external stimuli. They record natural energy that is reflected or emitted from the Earth's surface. The most common source of radiation detected by passive sensors is reflected ...

What is absolute pressure? - Setra Systems

· Absolute Pressure Defined. Absolute pressure is measured relative to a full vacuum. In contrast, pressure that is measured against atmospheric pressure ( also known as barometric pressure) is called gauge pressure. A full vacuum has an absolute pressure reading of 0 PSI A and average barometric pressure at sea level is ~ PSIA.

3 -- SENSOR SYSTEMS - Old Dominion University

Imaging vs. nonimaging sensors-- Remote sensing data are the recorded representation of radiation reflected or emitted from an area or object. When measuring the reflected or emitted energy, either imaging or nonimaging sensors can be used. Data from imaging sensors can be processed to produce an image of an area, within which smaller parts of the sensor's whole view are resolved ...

o2-sensor-testing

be aware that o2 sensor pre-conditioning is important, even on the newer styled heated o2 sensors. pre-condition the o2 sensor by raising the engine speed to 2000 rpm for about 15 seconds or so. the o2 sensor has to be above 600 º f. to be able to operate properly. long periods of idle time can render a non-heated or older o2 sensor too cold for it to function at all. at the same time, do not ...

Humidity - Wikipedia

Humidity is the concentration of water vapour present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present.. Humidity depends on the temperature and pressure of the system of interest.

Atmospheric sounding - Wikipedia

Atmospheric sounding or atmospheric profiling 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. Such measurements are performed in a variety of ways including remote sensing and in situ ...

Chapter 5 Measurement of Atmospheric Pressure

The atmospheric pressure is the force exerted by the weight of the Earth's atmosphere, expressed per unit area in a given horizontal cross-section. Thus, the atmospheric pressure is equal to the weight of a vertical column of air above the Earth's surface, extending to the outer limits of the atmosphere. Units In meteorology, atmospheric pressure is reported in hectopascals (hPa). 1 hPa ...
