Thank you all for the comments. It will definitively help me The data that I have is a time series on DBH and *some *heights for >40 years for around 65 trial locations covering entire Asutria. I am aware that DBH and height are very strongly correlated. My issue is... I want to explain the variations in growth that are caused by climate. Usually DBH strongly respond to management operation like thinning , felling etc . So How can I be sure that the variations in growth (if i take DBH as a indicator) is due to climate and not due to management.
The issue raised on examining the residuals seems interesting and useful, also on Dendrochronology. The issues raised on micro climate is definitely worth examining but I also agree with Thomas J. Givnish on his views on "mean annual anything". Its definitely not worthless because many of us tend to forget that modelling aims at simplifying things to an extent that we have just adequate set of information.
