air temperature

[′er ¦tem·prə·chər]
(meteorology)
The temperature of the atmosphere which represents the average kinetic energy of the molecular motion in a small region and is defined in terms of a standard or calibrated thermometer in thermal equilibrium with the air.
The temperature that the air outside of the aircraft is assumed to have as indicated on a cockpit instrument.

Air temperature

A measure of the heat energy contained in ambient air.

air temperature

The various types of temperatures include:
i. Indicated air temperature (IAT). The uncorrected reading from the free air temperature gauge.
ii. Basic air temperature (BAT). The indicated air temperature corrected for instrument error.
iii. True air temperature (TAT). The basic air temperature corrected for the temperature rise resulting from the heat of compression and skin friction. Also known as outside air temperature (OAT).
iv. Corrected mean temperature. The temperature of the static air; this is the same as ambient temperature and true air temperature.
v. Ram air temperature (RAT). The static air temperature plus temperature rise because of compressibility. It is usually 80% of true air temperature.
vi. Total air temperature (TAT). The temperature actually sensed by the temperature probe (i.e., BAT or basic air temperature). It is ambient temperature plus rise resulting from compressibility plus rise from skin friction. air terminal A facility on an airfield that functions as an air transportation hub and accommodates the loading and unloading of airlift aircraft and the intransit processing of traffic. The airfield may or may not be designated as an aerial port.

Thus, surface temperature closely follows ambient air temperature, while the amplitude of temperature waves decreases with increasing depth until it is completely damped out at a certain level.
The air handling unit serving the studied UFAD system has night time shutdown implemented, therefore, the effect of system scheduling on space temperature stratification was studied as well as the effect of outside air temperature.
The fundamental hypothesis of the overall research project was that the PV system, by providing cool air at the face region, would reduce the uncomfortable sensation of a warm head and would improve inhaled air quality, while the UFAD system, operating at relatively warm supply air temperature, would address the cold feet issue.
In their presentation at SAE's annual meeting, Toyota engineers argued that using room air temperature as a controlling index for an air conditioning system does not reflect the thermal state of a person.
EFD, Inc, A Nordson Company, announces the ProcessMate([TM]) 6100, a digital bench top reflow system that accurately controls air temperature within tight tolerances required for controlled solder paste reflow.
14 000 TR (49 238 kWth) would be delivered by the TIC system to the gas turbines running the compressors for the liquefaction process to ensure consistent inlet air temperature in the turbine fleet.
The new air conditioner we developed combines a compression cycle and a cycle that stops the compressor and circulates coolant with a pump (henceforth, "pump cycle") and operates by switching the cycle based on numerous conditions, such as the outdoor air temperature.
Between 1979 and 2006, the average summertime air temperature at 31 sites within 500 kilometers of the center of Lake Superior rose about 1.
Air temperature and volume controlled to maintain pellet quality.
Some chalked it up to tires that actually weren't warm enough on a day in which air temperature were 89 degrees and track temperatures soaring to 126 -- the hottest Indy 500 since 1953.
This provides the ability to control the air temperature of the chamber and record the internal temperature of the sample being tested, or a dummy sample exposed to the same temperature conditions.
