PowerPoint Presentation

The final sensor in our four sensor suite is the H2S sensor. H2S sensing capabilities are often times utilized in confined space or below grade settings, as the existence of hydrogen sulfide (better known as sewer gas) in such settings in sufficient concentrations can be fatal to personnel making entry without performing sufficient air monitoring.

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 ...

Barometer - Wikipedia

The concept that decreasing atmospheric pressure predicts stormy weather, postulated by Lucien Vidi, provides the theoretical basis for a weather prediction device called a "weather glass" or a "Goethe barometer" (named for Johann Wolfgang von Goethe, the renowned German writer and polymath who developed a simple but effective weather ball barometer using the principles developed by Torricelli).

Advantages and Disadvantages of Remote Sensing

· Remote sensing is unobstructive especially if the sensor is passively recording the electromagnetic energy reflected from or emitted by the phenomena of interest. This means that passive remote sensing does not disturb the object or the area of interest. Data collected through remote sensing is analyzed at the laboratory which minimizes the work that needs to be done on the field. …

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 …

Layers of the atmosphere | NIWA

The different layers of the atmosphere. The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.

What is Behind Rising Levels of Methane in the Atmosphere?

· Atmospheric methane levels have been rising, so Worden and colleagues applied some new analyses of satellite and ground-based data to more accurately pinpoint the sources. The concentration of methane in the atmosphere has risen sharply —by about 25 teragrams per year — since 2006. In recent years, different research teams have come up with viable but conflicting …

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 ...

Carbon Dioxide Absorbs and Re-emits Infrared Radiation ...

For example, nitrogen (N 2) and oxygen (O 2), which make up more than 90% of Earth's atmosphere, do not absorb infrared photons. CO 2 molecules can vibrate in ways that simpler nitrogen and oxygen molecules cannot, which allows CO 2 molecules to capture the IR photons. Greenhouse gases and the greenhouse effect play an important role in Earth's climate. Without greenhouse gases, our planet ...
