title: Monitoring of the atmospheric burdens of CH4, N 2O, CO, CHCIF 2 and CF 2Cl 2 above Central Europe during the last decade.
abstract: 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 monitored routinely since 1984. The observed temporal evolutions in the columns of CH4, N2O, CO, CHClF2 (HCFC-22) and CF2Cl2 (CFC-12) are reported here as typical examples of this monitoring effort which is conducted within the frame of "Global Change" and "Network for the Detection of Stratospheric Change" programs.
