The development of SilviScan-3TM, measurements of cell characteristics, wood density and wood microfibril angle, and boundary marking of ring with the SilviScan-3TM were introduced. Relationships between six wood properties (ring cell diameter, cell wall thickness, width, density, microfibril angle and modulus of elasticity) of Picea crassifolia and temperature and precipitation were analyzed. The six wood properties are significantly correlated with monthly mean temperature and monthly precipitation, while the significantly correlated time is different. Moreover, ring microfibril angle and cell characteristics record more climate signals than ring width and density, which are commonly used as climate proxies. There are several advantages of SilviScan-3TM for research on climate change, e.g., high resolution measurements, multiple property parameters measurement from a same sample and precisely marking ring boundary.
