The data from this time up to 1983 indicate an increasing trend at a rate of about 1% per year (Rasmussen and Khalil, 1986; Steele et al., 1987; Blake and Rowland, 1988). The most recent measurements indicate a slowing of the global accumulation of atmospheric CH. (Khali

Since that time, more detailed and extensive data sets have allowed estimation of sources and sinks of methane on the global scale. As attempts are made to refine these estimates, the value of the current databases will be greatly increased,
