Year = Calendar year of tree ring; ST_ID = Unique ID for each subject tree; Canopy_Class = Canopy position of subject tree, either dominant (DO) or intermediate (IN); ST_DBH = diameter at breast height of subject tree; HCI = Hegyi's Competition Index; DIB = Diameter inside bark; Comp_Class = Categorical grouping based on HCI; SW = avg. distance (cm) of sapwood on increment cores; Age = age at breast height when tre was sampled; Stand_ID = Unique ID for each stand; PLW_Class = Categorical grouping based on PLW; BAI = Basal area increment; BAI.rwi = Index based on BAI; EWA = Earlywood area increment; EWA.rwi = Index based on EWA; LWA = Latewood area increment; LWA.rwi = index based on LWA; PDSI = Palmer Drought Severity Index for NCDC WA Div 9; PLW = Proportion of latewood
