Title:Mean Temperature Biases As a Function of the Time of Observation
Author(s):Head, David E.
Subject(s):Mean Temperatures
upper Great Plains
Abstract:Hourly and daily temperature data for ten National Weather Service stations in the Midwest and upper Great Plains states were used to determine long-term time of observation biases on mean temperatures derived from 24-hour maximum and minimum values. Although differences in the magnitude of the bias were found from station to station, good continuity was exhibited across the area in question. Generally the biases for any given month show a stronger longitudinal than latitudinal correlation. Daily mean temperatures calculated from 24-hour readings made near 0700 local time tend to be lower than a midnight-to-midnight reading. Observations made during the afternoon tend to be higher, with magnitudes of 0.5 C to 1.0 C common.
