Gaseous Attenuation

Calculating Atmospheric Attenuation A really good model for atmospheric gas attenuation is available from the ITU-R in ITU-R P.676-6 Attenuation by Atmospheric Gases.

Atmospheric Gases

The majority of atmospheric gases are classified as unreactive or inert, and it is only the oxidising gases, oxygen and carbon dioxide, that react readily with other elements. Separating the Gases The main atmospheric gases – oxygen, nitrogen and argon – and the rare gases are generally captured by reducing the temperature of air until each component liquefies and can be separated.

Nitrogen Fixation

Nitrogen fixation also refers to other biological conversions of nitrogen, such as its conversion to nitrogen dioxide. Nitrogen fixation is a process by which nitrogen (N 2) in the atmosphere is converted into ammonia (NH 3).Atmospheric nitrogen or elemental nitrogen (N 2) is relatively inert: it does not easily react with other chemicals to form new compounds.

Nitrogen

Colorless, odorless, tasteless, and nontoxic, nitrogen exists as a non-flammable gas at atmospheric temperatures and pressures. A specific gravity of .9669 makes nitrogen slightly lighter than air. When cooled to its boiling point of -320F, nitrogen becomes a colorless liquid which can, in turn, be compressed into a colorless, crystalline solid. Get price

Nitrogen in the Environment: Nitrogen's Most Common

Nitrogen is important for all plants to live, and it comes in many forms. Although the atmosphere is mostly made up of nitrogen, it is in the form of a gas known as dinitrogen N2. Plants cannot use this form. Dinitrogen, or atmospheric nitrogen, can also be found in the soil. In addition to dinitrogen, other inorganic and organic forms exist in the soil as well. Organic forms of nitrogen make Get price

Atmospheric Composition

Nitrogen is removed from the atmosphere and deposited at the Earth's surface mainly by specialized nitrogen fixing bacteria, and by way of lightning through precipitation. The addition of this nitrogen to the Earth's surface soils and various water bodies supplies much needed nutrition for plant growth. Get price

Simulation of a wire

In this work, we are going to perform a simulation of a wire-cylinder-plate positive corona discharge in nitrogen gas, and compare our results with already published experimental results in air for the same structure. We have chosen to simulate this innovative geometry because it has been established experimentally that it can generate a thrust per unit electrode length transmitted to the gas Get price

Nitrogen

Nitrogen gas is taken from the atmosphere and converted by bacteria into nitrogen compounds that plants and animals can use.EPA Nitrogen is an essential part of life. Plants, animals and bacteria all use nitrogen in fundamental building blocks called amino acids, and these are joined together to Get price

Oxygen gas (O 2), the second most abundant, makes up about 21% of the volume of the dry atmosphere. Dry atmosphere simply refers to a theoretical atmosphere that contains no water vapor. Together, nitrogen and oxygen make up about 99% of the air we breathe. Get price

Biomonitors of atmospheric nitrogen deposition:

Abstract Atmospheric nitrogen deposition is the third largest cause of global biodiversity loss, with rates that have more than doubled over the past century. This is especially threatening for tropical regions where the deposition may soon exceed 25 kg of N ha −1 year −1, well above the threshold for physiological damage of 12–20 kg of N ha −1 year −1, depending on plant species and Get price
