see Pressure, Barometric.
Pressure is the measurement of a force (weight) on a per unit area. The barometer measures the force our atmosphere exerts on a per-unit area of surface, or the "weight of the air".
is the absolute atmospheric pressure existing at the surface of the earth. It is the weight of a unit column of air above the point of measurement. It varies with altitude and, at any given location, with moisture content and weather.
The atmospheric pressure at a given point due to the gravitational force on the column of air above it.
The pressure of the atmosphere expressed in units of mbars, psig, or Hg (inches of mercury).
The reading in inches of mercury (in Hg), showing atmospheric pressure at a given location.
atmospheric pressure as indicated by a barometer
Atmospheric pressure, as measured with a barometer.
(BaroPr): Barometric Pressure is atmospheric pressure as measured by the U.S. Army Corps of Engineers water quality monitoring site, given in mmHg.
The total pressure exerted by the atmosphere. This term is synonymous with "atmospheric pressure."
(Atmospheric pressure) The amount of pressure exerted by the atmosphere at a specific point. We measure the weight of the air with a BAROMETER.
See Air Pressure
The measurement of pressure set by the atmosphere.
The pressure exerted by the atmosphere as a consequence of gravitational attraction exerted upon the "column" of air lying directly above the point in question. The measurement can be expressed in several ways. One is in millibars. Another is in inches or millimeters of mercury (Hg). Also known as atmospheric pressure.
The atmospheric pressure as read on a barometer. Usually given in units mB (millibars).
See Atomspheric Pressure
Is the absolute atmospheric pressure existing at any given point in the atmosphere. It is the weight of a unit column of gas directly above the point of measurement. It varies with altitude, moisture and weather conditions. ( 099)
The atmospheric pressure at a specific place according to the current reading of a barometer.
the rising and falling of the barometer that forecasts the coming weather by either rising or falling atmospheric pressure. It is identified as high or low system that indicates clear or cloudy conditions. A low-pressure system may carry precipitation. A high-pressure system is typically void of precipitation.
(also known as atmospheric pressure) the pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned

same as atmospheric pressure with the exception that it varies with the weather.
The barometer installed at a station used to collect atmospheric pressure data. cla
The pressure exerted by the atmosphere at a given point. Its measurement can be expressed in several ways. One is in millibars. Another is in inches or millimeters of mercury (Hg). Related term: atmospheric pressure
Barometric pressure is the absolute pressure exerted by the atmosphere.
The basic unit of pressure is the millibar [Mb]. Air at standard pressure [14.7psi] is capable of supporting a column of mercury to a height of 29.99" or 1013.2Mb. Once airborne, altimeters are set to indicate 1013.2Mb which ensures that all aircraft operate under an agreed international set of standard conditions relative to each other wherever they are in the world. Barometric pressure reduces with height.
Atmospheric pressure as determined by a barometer usually expressed in inches of mercury.
The downward pressure, at any given point in the atmosphere, of the gases directly above that point. Average pressure globally at sea level is 1,013,000 dynes per centimeter squared or 760 torr. This is defined as one atmosphere.

another term for air pressure
The actual pressure value indicated by a pressure sensor.
Barometric pressure is the weight of the column of air that extends from the ground (or water's surface) to the top of the atmosphere. It is also called air pressure. Air pressure is measured by a barometer. 29.92 is the average air pressure at sea level. Barometric pressure is very low in a hurricane.
Barometric Pressure is atmospheric pressure at the site, given in mm Hg. It represents an average of hourly measures. Barometric Pressure is measured at Water Quality Monitoring stations in the forebay and tailrace of most projects (see Data Sites Map) and other key locations in the basin. Prior to 1995, the data are from a variety of sources within the U.S. Army Corps of Engineers.
The pressure exerted by the weight of the earth's atmosphere, equal to one bar, 100 kilopascals, or 14.7 psi (often rounded off to 15 psi) at sea level. Barometric pressure changes with the weather and with altitude. Since it affects the density of the ai
