In the tropics, they take up water from the deep soil and release it as vapor in the air.
Absolute humidity, on the other hand, refers to the actual amount of water vapor in the air regardless of saturation.
The technology has advanced to the point where we are getting that much closer to fully solution-processed OLED devices, and new materials such as our non-aqueous HIL are a key requirement in the transition from vapor to solution processing.

In 1863 the Irish scientist John Tyndall determined that carbon dioxide and water vapor trapped more heat in the atmosphere as their concentrations increased.
Increased water vapor in the air is a consequence of higher temperatures.
Now most of that increase occurred after 1970, and it's an indication that there's more water vapor in the atmosphere so that these storms get invigorated.
Butane, which has an RVP of 52 psi, can be blended into gasoline in higher proportions in the winter because the vapor pressure allowance is higher.
During the spill, three shifts of employees monitoring the pipeline from the command center in Edmonton, Alberta, received multiple warning alarms, but dismissed them as being caused by column separation, or bubbles of vapor in the pipeline, according to the NTSB investigation.
This finding ties in with the revelation of hydrogen on Vesta, because the likeliest explanation for the indentations on the surface is that hydrogen, which is likely bound up in minerals there, is released in the form of water vapor when the material is heated up by impacts.
As a result, the astronomers demonstrated in their research that the JWST should be able to detect the presence of water vapor and oxygen in an atmosphere in just a few hours of observation.
Scientists have previously established the existence of water on Mars in the form of ice at the poles and water vapor, and pointed to geological features that appear to have been carved by water ages ago.
Using a particle accelerator, he demonstrated that cosmic rays colliding with molecules in the atmosphere can, in fact, cause gaseous water vapor to condense into cloud-forming droplets.
There are a few drawbacks to the mouse-method though, as the release of vapor from mines can depend on conditions in the ground, leading to detection some meters from the actual device, or no detection at all.

Treatment continues at the sites today, with vapor barriers in place, so-called slurry walls going down 40 feet into the earth, well sucking up water to be treated, and systems operating to extract toxins from the air and water.
FORBES: Google Buildings Polluted With Toxic Vapors From Chemical Spills
Though Vapor Corp is not yet profitable, I had a chance to learn a little more about the industry in a chat with Vapor Corp CEO Kevin Frija.
The Grenoble study authors did not factor in influences the warming oceans would have had upon evaporated water vapor, that primary atmospheric greenhouse gas.
FORBES: The Feverish Hunt For Evidence Of A Man-Made Global Warming Crisis
Formerly, the water from the toilets had flowed out in a stream, but now it was thin vapor the speed of the train tore it into prickly spray.
Right on cue, Wentz proclaims that the mercury vapor reading hits 61 in just a few seconds.
FORBES: Dr. Oz Is Worried About Your Teeth. Should You Worry Too?
The IPCC computer models predict a much larger warming, three degrees Celsius or even more, because they assume changes in water vapor or clouds that supposedly amplify the direct warming from CO2.
For an earlier collection, the designers printed the cloth in bright swirls with an inkjet printer, then steamed the reverse side with "a fog of aluminum vapor" to give it a reflective side and enhance the colorful print, he says.
WSJ: Polyester Is Back in Style at Alexander Wang, Talbot Runhof, Akris
My background is in the creation of magnetic recording heads and media using physical vapor deposition technology.
Injected into the exhaust stream, the solution's ammonia reacts in the de-NOx catalyzer to form nitrogen and water vapor.
WSJ: 2013 Porsche Cayenne Diesel Review: Only Geeks Need Apply | Rumble Seat by Dan Neil
He lay in bed with only his face outside the covers, making clouds of vapor.
The much larger warmings forecast by IPCC require a major increase in atmospheric water vapor and warming clouds.
FORBES: What Happens When You Rub Two Climatologists Together?
His breath turned immediately to vapor outside his mouth, and he felt as if the air in his lungs were lost forever.
Dover Harbour Board (DHB) said Barco de Vapor, which currently operates from Ramsgate in Kent, had applied to berth the MV Joline from the Eastern Docks.
Of course, all these hysterics are based on nothing more than speculation and rumors, since basically no one's ever seen a whitespace device in use -- maybe if one of the giant companies backing the tech would actually demo some of this vapor, people wouldn't be so nervous about it.
