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 ±...
