ATMOSPHERIC CARBON DIOXIDE MEASUREMENTS AT SYOWA STATION, ANTARCTICA, 1984-1988
Precise and continuous measurements of atmospheric CO_2 concentration have been continued at Syowa Station (69°00'S, 39°35'E), Antarctica since February 1984. Diurnal CO_2 variation was hardly observable throughout the year. The secular CO_2 trend was variable with time, showing slow incre...
