A INTRODUCTION TO THE GLOBAL CARBON C - Globe …
globecarboncycle.unh.educan cycle carbon among various pools within ecosystems and eventually releases it back to the atmosphere. Viewing the Earth as a whole, individual cycles like this are linked to others involving oceans, rocks, etc. on a range of spatial and temporal scales to form an integrated global carbon cycle (Figure 2). On the shortest time scales, of

Part 1: Oxidation and OH radicals - Harvard University
courses.seas.harvard.eduthe reaction of nitrogen monoxide (NO) with the hydroperoxy radical (HO 2) or the reaction of alkenes with ozone. The scheme on the left shows how OH chemistry is fundamentally linked with the day-time reaction cycles of the nitrogen oxides. How much OH is formed? Since OH is an extremely reactive radical it reacts as soon as it is formed.

In polluted air, other reactants are available (acid rain problems associated with the release of sulfuric acid from coal-fired power plants, sulfur dioxide and smoke emissions, nitrogen oxides from vehicle exhaust). Table 1 gives a list of weathering reactions that have been recognized.
