| Abstract | Observations were made on the mean daily air temperature and on soil temperature at depths 5 and 10 cm below the surface during the period 23 December 1956 to 31 October 1962. Average annual temperatures were calculated for the observation levels at intervals of one-seventh of a year. The average annual air temperature was observed to vary between 4.90 and 7.37 degrees C; the average annual 10-cm soil temperature between 7.86 and 9.00 degrees C; and the difference between them between 1.27 and 3.25 C degrees. The analysis indicated that the snow cover was the principal reason for the difference between average annual air and soil temperatures at the Ottawa site. The partitioning of surface heat between convection and evaporation or evapotranspiration, and the variation with time of the surface heat transfer coefficients probably contributed between 0 and 1 C degree to the difference. |
