Abstract
Data was collected on air temperature every 20 minutes using a YSI 44036 thermistor with a Lakewood data logger at three stations at different climatic and latitudinal situations. Mean daily air temperature was calculated from the data in three ways, viz.: dividing the total of 72 readings by 72 (the integration method), adding the minimum and maximum temperatures and dividing by 2 (the International Standard), and adding the 0800 and 1700 hour readings and dividing by 2. The integration method provides a lower reading for most monthly and yearly data, and there are substantial differences (up to 7C) for mean daily air temperatures calculated by different methods. These are largest in winter and least in summer. Differences increase with continentality and the integration method clearly gives a more accurate measure of heat flux and climatic change, and should be calculated along with the minimum-maximum average for automated stations.
