The CO2 data measured over times between 11:00 Japan Standard Time (JST) and 16:00 JST (C N ) were considered to be representative of the air (within a few ppmv) in the planetary boundary layer. To evaluate the representative CO2 level on a spatial scale larger than that of the C N record, the CO2 data with hour-to-hour variation less than 1 ppmv were selected (C P ). Comparison of these data with those of Ryori (39°02′ N, 141°50′ E), a continental station operated by the Japan Meteorological Agency, indicates that the C P record provides a representative CO2 level in the air on spatial scales of at least a few hundred kilometers. The C N record allows an investigation of the internanual changes in photosynthesis/respiration against changes in climatological parameters. Within a small temperature anomaly (ca.±1 °C) respiration is sensitive to the temperature change, while photosynthesis is less sensitive. When the temperature anomaly is large, however, photosynthesis and respiration tend to be competitive.
