Natural variations in the deuterium composition of carbon-bound hydrogen of cellulose nitrate from tree rings have been measured. Trees from Edmonton have been analysed in detail and the δD values of 5-year groups of rings show a strong temporal correlation with mean annual temperature at the growth site. This is shown to result from the cellulose isotopic composition being related to the isotopic composition of soil water used during photosynthesis. The soil water is in turn related to meteoric water which at this growth site appears to correlate temporally with mean annual temperature. Similar measurements from trees which grew in various areas of North America show a strong spatial correlation between δD of cellulose and mean annual temperature. The spatial functional relationship between δD values and mean annual temperature at the growth site (t) is found to be δD = 5.5t - 130‰swhich compares with the spatial relationship between δD of meteoric water and mean annual air temperature which is δD = 5.6t - 100‰.
