Assessment of cf4 transmitter

Assessment of cf4 transmitter

In comparison to the stratospheric values of CF4 inferred from the ATMOSpacelab 3 mission of 1985, the 1994 concentrations are consistent with an exponential increase of (1.6 +/- 0.6)% yr (exp -1). This increase is discussed with regard to previous results and likely sources of CF4 at the ground.

Eluforsen-induced increases in chloride efflux rates were slightly smaller than those observed for CF4
