Pertti Hari, Markku Kanninen, Seppo Kellomäki, Olavi Luukkanen, Paavo Pelkonen, Raimo Salminen, Heikki Smolander. (1979). An automatic system for measurements of gas exchange and environmental factors in a forest stand, with special reference to measuring principles. Silva Fennica vol. 13 no. 1 article id 5019. https://doi.org/10.14214/sf.a14873

A system for measuring the net photosynthesis, transpiration and environmental factors within the canopy and ground cover vegetation is described. The system operates continuously throughout the growing season in a young Scots pine (Pinus sylvestris L.) stand. A data-logging unit controls the system and carries out the measurements on the readings of the sensors of photosynthesis, transpiration, light intensity outside the canopy, light climate inside the assimilation chambers, and dry and wet temperatures from selected points. These measurements are shown digitally and automatically punched onto paper tape.

The PDF includes a summary in Finnish.
