Global tropospheric ozone variations from 2003 to 2011 as seen by SCIAMACHY
An analysis of the tropospheric ozone (O 3 ) columns (TOCs) derived from SCIAMACHY limb-nadir-matching (LNM) observations during the period 2003–2011, focusing on global variations in TOC, is described. The changes are derived using a multivariate linear regression model. TOC shows changes of −0.2 ±...

An analysis of the tropospheric ozone (O 3 ) columns (TOCs) derived from SCIAMACHY limb-nadir-matching (LNM) observations during the period 2003–2011, focusing on global variations in TOC, is described. The changes are derived using a multivariate linear regression model. TOC shows changes of −0.2 ± 0.4, 0.3 ± 0.4, 0.1 ± 0.5 and 0.1 ± 0.2 % yr −1 , which are not statistically significant at the 2 σ level in the latitude bands 30–50° N, 20° S–0, 0–20° N and 50–30° S, respectively. Tropospheric O 3 shows statistically significant increases over some regions of South Asia (1–3 % yr −1 ), the South American continent (up to 2 % yr −1 ), Alaska (up to 2 % yr −1 ) and around Congo in Africa (up to 2 % yr −1 ).
