The CO2 in the atmosphere is in contact with water vapor and rain droplets forming CO2 · H2O · HCO3 and CO²3. Global precipitation is about 505 x 1015 kg/a. Based on theoretical calculation for unpolluted air and measurement observations, we estimated that 100--270 x 1012 gC/a are scavenged from the air by global precipitation. This roughly equals carbon emissions from volcanic sources or 2-6 per cent of current CO2 emissions. An inventory-based estimate on carbon removal in northwestern Europe supports the above calculation on global scare. With increasing CO2 concentration in the air, precipitation scavenging may increase. [ABSTRACT FROM AUTHOR] |
