Carbon monoxide (CO) mixing ratios in the middle troposphere have been examined for short periods of time by using the Measurement of Air Pollution from Satellites (MAPS) instrument. MAPS measures CO from a space platform, using gas filter correlation radiometry. During the 1981 and 1984 MAPS flights, measurement validation was attempted by comparing space measurements of CO to those made in the middle troposphere from aircraft. Before the 1994 MAPS flights, a correlative measurement team comprised of eleven laboratories was assembled to provide NASA with results of their CO field measurement programs during the April and October 1994 missions. To maximize the usefulness of the correlative data, team members agreed to participate in an intercomparison of CO measurements.

The correlative data provide an internally consistent, ground-based picture of CO in the lower atmosphere during spring and fall 1994. The data show the regional importance of two CO sources, fossil-fuel burning in urbanized areas and biomass burning in regions of the Southern Hemisphere. WDC-A database
