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 time and/or constant:
“Some fear that if parents start listening to their own wants and needs they will neglect their children. It is our belief that children are in fact far less likely to be neglected when their parents’ needs—for support, for friendship, for decent work, for health care, for learning, for play, for time alone—are being met.”
—Wendy Coppedge Sanford. Ourselves and Our Children, by Boston Women’s Health Book Collective, introduction (1978)
“We can never establish with certainty what part of our relations with others is the result of our emotions—love, antipathy, charity, or malice—and what part is predetermined by the constant power play among individuals.”
—Milan Kundera (b. 1929)
