Ring-porous tree’s ring width is used to reconstruct climate, but it is often incomplete and based on weak signal strength. Image analysis programs can be used to examine parameters considering vessel and cell properties with relatively high efficiency and accuracy. This study examines the signal strength of these parameters in predicting climatic features such as monthly precipitation and gage height. To do this, correlations were drawn between the parameters produced by the image analysis program and recorded climate measurements. Preliminary results show a potential to refine climate chronology in seasons of relatively high signal strength in ring width and form chronologies in seasons where ring width shows little to no sensitivity. Vessel width and cell width initially show moderate signal strength in September, October, and November, typically weak months for ring width signal strength. These parameters can help create a holistic construction of annual climate data.
