Figure 4.11: Observed seasonal
surface CO abundance (ppb, thick black lines) at Cape Grim (CGA: 40°S, 144°E,
94 m above mean sea level), Tae Ahn (KOR: 36°N, 126°E, 20 m), Mauna Loa
(MLH: 19°N, 155°W, 3397 m), Alert (ALT: 82°N, 62°W, 210 m), and
Niwot Ridge (NWR: 40°N, 105°W, 3475 m) are compared with the OxComp model
simulations from Y2000, see Figure 4.10.
