R. Zander et al., MONITORING OF THE ATMOSPHERIC BURDENS OF CH4, N2O, CO, CHCLF2 AND CF2CL2 ABOVE CENTRAL-EUROPE DURING THE LAST DECADE, Environmental monitoring and assessment, 31(1-2), 1994, pp. 203-209
Based on high spectral resolution infrared solar observations made at
the International Scientific Station of the Jungfraujoch, Switzerland,
total vertical column abundances of 18 atmospheric gases have been mo
nitored routinely since 1984. The observed temporal evolutions in the
columns of CH4, N2O, CO, CHClF2 (HCFC-22) and CF2Cl2 (CFC-12) are repo
rted here as typical examples of this monitoring effort which is condu
cted within the frame of ''Global Change'' and ''Network for the Detec
tion of Stratospheric Change'' programs.
