8. Glossary of Terms
Term
Definition
Absolute Barometric
Pressure
Relative barometric pressure, corrected to sea-level. To compare
pressure conditions from one location to another, meteorologists correct
pressure to sea-level conditions. Because the air pressure decreases as
you rise in altitude, the sea-level corrected pressure (the pressure your
location would be at if located at sea-level) is generally higher than your
measured pressure.
Accuracy
Accuracy is defined as the ability of a measurement to match the actual
value of the quantity being measured.
HectoPascals (hPa)
Pressure units in SI (international system) units of measurement. Same
as millibars (1 hPa = 1 mbar)
Hygrometer
A hygrometer is a device that measures relative humidity. Relative
humidity is a term used to describe the amount or percentage of water
vapor that exists in air.
Inches of Mercury (inHg)
Pressure in Imperial units of measure.
1 inch of mercury = 33.86 millibars
Radio Controlled Clock
(RCC)
The United States government distributes time-of-day to the public
using radio broadcasts. The low frequency (LF) station WWVB is
located in Fort Collins, Colorado and broadcasts on 60 kHz. The high
frequency (HF) stations WWV and WWVH are located in Colorado and
Hawaii respectively, and broadcast on five different frequencies ranging
from 2.5 to 20 MHz. At least one HF signal should always be usable at
any given time anywhere in the United States.
Range
Range is defined as the amount or extent a value can be measured.
Relative Barometric
Pressure
Measured barometric pressure relative to your location or ambient
conditions.
Resolution
Resolution is defined as the number of significant digits (decimal
places) to which a value is being reliably measured.
Wind Vane
A wind vane is a device that measures the direction of the wind. The
wind vane is usually combined with the anemometer. Wind direction is
the direction from which the wind is blowing.
