Atmospheric carbon monoxide levels decreasing in mid-Atlantic region
.... It is an important link controlling theoxidizing capacity of the atmosphere, through its chemical interaction with thehydroxyl radical (OH). The mean level of carbon monoxide at Big Meadows in 1988-1989 was 204 ppbv, ascompared with 166 in 1997, a decrease of 4.8 ppbv per year or 22.9 percenttotal.
