Hello everyone, I’m Eliane Gomes-Alves. I have been working at ATTO since 2015 with measurements of plant emissions of Volatile Organic Compounds (VOC), which we can all call “the forest scent”. We measure these compounds because they play an important role in the forest-atmosphere interactions, effecting biogeochemical cycles and climate.
To sample VOC emissions, we use equipment that was originally developed to measure gas exchanges between the air and plant leaves.
It is called IRGA – infrared gas analyzer. The IRGA measures gas exchanges to calculate photosynthesis and transpiration of plants. This portable equipment has a chamber, where we can enclose the leaf.
