Abstract
Comparison has been made of the average of daily minimum and maximum with a mean of continuously recorded temperature at 200, 50, 5 and -5 cm height using different methods and under different conditions. At 200 cm the average was also estimated from 3 daily temperature observations. The temperature was recorded by thermographs and by a punch tape recorder. Mercury-in-steel as well as resistance thermometers were used. Slightly better agreement was found between the 10 day or monthly mean and average temperature estimated from the daily t08, t14 and t21 . The temperature variation was greatest close to soil surface, and the average of minimum and maximum was higher than the mean temperature. Sufficiently accurate, absolute temperature figures could not be obtained by the thermographs. The use of minimum and maximum thermometers requires readings only once a day sometime in the interval between the occurrence of minimum and maximum temperature.This publication has 0 references indexed in Scilit:
