The Geophysical Monitoring for Climatic Change (GMCC) program, which has operated for eight years, is described. The most significant change in the GMCC operational program in 1979 was the initiation of 10 additional CO2 flask sampling stations. Continuous measurement of CO2 and aerosol scattering at four wavelengths, using a nephelometer, was begun at the South Pole station at the end of 1978 and continued throughout 1979. A filter collection system was installed at the Barrow station to make possible the determination of the mass of the carbonaceous aerosols. Early results show that graphitic carbon makes up a significant part of the arctic haze, and because of its optical absorptivity, it may cause a significant contribution to the radiative energy budget. At the Mauna Loa Observatory a new cooperative measurement program to observe the chemical composition of aerosols was initiated.
