Learn about water vapor in the air. Study the measurement of water vapor in the air and uncover how to measure vapor pressure, humidity, mixing...
The amount of water vapor in the air influences all weather. How water vapor gets into the air is relative to where one is geographically. How does humidity work and what causes humidity? Earth is a self-contained machine that circulates its water. This cycle is known asthe water cycle. ...

of water vapor from a moist gas; 2) the addition of water vapor to produce a saturated gas; 3) the reversible sorption of water vapor by a sensor; 4) the measurement of a physical property of a gas; 5) attaining the liquid-vapor or the solid-vapor equilibrium state of the water ...
Though the necessity of measuring the vertical flux of heat and water vapor, brought about by eddy movement in the lower atmosphere, has long been recognized, no direct method of determining these important quantities has previously appeared. The apparatus described here provides a continuous record,...

One of the most important corrections desired is due to the presence of water vapor in the atmosphere. Due to the high variability of water vapor in space and time, its real-time monitoring is necessary, and it is traditionally carried out using concurrent observations from a passive microwave...
the water container headspace and air chamber are separated by such plate-like material sample for carrying out such measurements under stationary air flow conditions according to detecting an absolute humidity increase of 1% in an air chamber atmosphere, and where determinations of water vapor ...
allows you to determine its vapor pressure curve. Besides this, the enthalpy of vaporization of the liquid can be determined from such measurements using the Clausius–Clapeyron equation. In this article, we show how such measurements are performed in a high-pressure DSC using water as an ...
