Dendrochronology or tree-ring dating is the scientific method of dating based on the analysis of patterns of tree rings, also known as growth rings. During sediment transport, exposure to sunlight 'zeros' the luminescence signal. Careful sampling under dark conditions allows the sediment to be exposed to artificial light in the laboratory which releases the OSL signal.

Tree rings provided truly known-age material needed to check the accuracy of the carbon dating method. Calibration curves have a dendro timescale on the x-axis and radiocarbon years on the y-axis. At higher temperatures, CO 2 has poor solubility in water, which means there is less CO 2 available for the photosynthetic reactions.
