3D View of CO2 over Asia (IMAGE) National Institute for Environmental Studies Caption Three-dimensional view of the CONTRAIL CO2 observations (left August and right September). Obvious is distinct CO2 depletion within the Asian summer monsoon anticyclone (thick red arrow) and the low CO2 extends from the near-surface layers (blue pillar over Delhi, India). Colors on the upper panel indicate monthly average CO2 concentrations (atmospheric increasing trend subtracted) obtained from measurements at cruising altitudes (approx. 10 km). The black arrows show monthly averaged wind. In addition, measurements during ascent/descent over airports illustrate vertical profiles (colored pillars). The lower panel indicate CO2 emissions (red) and uptakes (blue) by the terrestrial biosphere. Credit CONTRAIL team Usage Restrictions Credit required.
