A time constant is the amount of time it takes for a meteorological sensor to respond to a rapid change in a measurand until it is measuring values within the accuracy tolerance usually expected of the sensor.
This most often applies to measurements of temperature, dewpoint temperature, humidity and air pressure. Radiosondes are especially affected due to their rapid increase in altitude.

Famous quotes containing the words constant and/or time:
“The East is the hearthside of America. Like any home, therefore, it has the defects of its virtues. Because it is a long-lived-in house, it bursts its seams, is inconvenient, needs constant refurbishing. And some of the family resources have been spent. To attain the privacy that grown-up people find so desirable, Easterners live a harder life than people elsewhere. Today it is we and not the frontiersman who must be rugged to survive.”
—Phyllis McGinley (1905–1978)
“The secret of a long life is knowing when it’s time to go.”
—Michele Shocked (b. 1962)
