Air Masses refer to the different layers of the Earth's atmosphere through which solar radiation passes. In the context of solar energy, the standard air mass is denoted as AM 1.5. AI generated definition based on: Progress in Quantum Electronics, 1998 About this pageSet alert Discover other ...
and minute amounts of rare gases (as helium), that surrounds the earth with half its mass within four miles of the earth's surface, that has a pressure at sea level of about 14.7 pounds per square inch, and that has a density of 1.293 grams per liter at 0°C and 760 mm pressure ...
Expressions are derived for the horizontal and vertical components of the wind, the temperature, and the mass of water vapor condensed when air flows over a long mountainous ridge. The growth of solid precipitation particles in the or... PV Hobbs,RC Easter,AB Fraser - 《Journal of the Atmosp...
The initial model was fitted on 12 manually selected days and was of the following form:Bnc=Ioexp(−0.16−0.22·AM)This early model assumed a constant Linke turbidity coefficient value of 3. When comparing this model against clear days manually selected from the 7 data banks, the diurnal...

(WHO, 2006) are based on fine particle mass concentration (PM2.5) because these particles penetrate deep into the lungs. However most routineair quality monitoringis of PM10, which includes PM2.5as a subset, so equivalent PM10guidelines are also set assuming that half the mass of PM10is ...
The cells were washed twice by letting the filters float on water for 5 min. The fixed cells were harvested as described in the section called Cell quantification. The resulting cell suspension was stored at 4 °C until measurements of the buoyant cell mass. For the measurements, two ...

The atmosphere is the least understood biome on Earth despite its critical role as a microbial transport medium. The influence of surface cover on composition of airborne microbial communities above marine systems is unclear. Here we report evidence for
Those with some external air supply are generally termed “supercharged.” The horsepower developed by an engine is dependent on its supply of air. The moreair masscontained in a cylinder at ignition the more fuel that can be burned and the more horsepower that will be developed by the ...
