Within urban ecosystems are strong anthropogenic
emissions of CO2 as well as significant CO2 sinks
associated with vegetation. CO2 profiles and net flux of CO2
(NEE) over Denver
was measured over a multi-year period and compared with certain component
fluxes (soil surface net flux, and emissions from fossil fuel combustion). CO2
concentration and NEE typically exhibits a diurnal trend, apparently due to
emissions from transportation and sequestration by vegetation.
