Laser Photoacoustic Detection of CO(2) in Old Disc Tree-Rings
A homemade CO(2)–laser photoacoustic spectrometer has been used for monitoring CO(2) in gas samples extracted under vacuum from the wood of old spruce disc tree-rings for a ∼60 year series. The experimental results show that (1) the CO(2) concentration exhibits annual trends correlated with an incre...
