Available in PDF, EPUB and Kindle. Book excerpt: As part of a larger experiment to measure the cosmic microwave background radiation spectrum, frequent simultaneous measurements of the microwave thermal emission from the earth's atmosphere were made at three fixed frequencies, namely, 10 GHz, 33 GHz and 90 GHz. We performed these measurements at two separate locations, Berkeley and White Mountain, which greatly differed in altitude and climatic conditions. Typical values measured in Berkeley of the atmospheric antenna temperature during good weather are 3.13 +- 0.30°K, 12.3 +- 0.3°K and 34.6 +- 0.5°K, for 10, 33, and 90 GHz respectively. Corresponding values measured at White Mountain are 1.15 +- 0.1°K, 4.51 +- 0.18°K and 11.0 +- 0.2°K. Because the measurements are simultaneous in nature, correlations between the measurements taken at the various frequencies provide constraints on models of the microwave emission of the earth's atmosphere, especially models describing atmospheric emission as a function of precipitable water content.

Download or read book Measurement of Atmospheric Emissions written by Heikki Torvela and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the threat of a possible global climate change and the greenhouse effect caused by constituents of anthropogenic origin in the atmosphere, air quality has become a major environmental issue. As a consequence, emissions into the atmosphere need to be monitored and controlled. Measurement of Atmospheric Emissions presents technologies for emission control and analysis from industrial and energy plants. The author explains the physical and chemical basis before proceeding to the practical performance. This publication provides the reader with the knowledge necessary to critically analyze and investigate emission measurement techniques. It will be of great interest to researchers and engineers in the fields of environmental technology and air pollution control. It will assist in the choice of the most appropriate instruments for various purposes and circumstances.
