Solar UV irradiation-induced production of N<sub>2</sub>O from plant surfaces - low emissions rates but all over the world
UV-induced carbon monoxide emission from sand and living vegetation
The global burden of carbon monoxide (CO) is rather uncertain. In this paper
we address the potential for UV-induced CO emission by living terrestrial
vegetation surfaces. Real-time measurements of CO concentrations were made
with a cavity-enhanced laser spectrometer connected in closed loop to either
a chamber on a field of grass or a plant-leaf scale chamber. Leaves of all
plant species that were examined exhibited emission of CO in response to
artificial UV radiation as well as the UV component of natural solar
radiation. The UV-induced rate of CO emission exhibited a low dependence on
temperature, indicating an abiotic process. The emission of CO in response to
the UV component of natural solar radiation was also evident at the natural
grassland scale
