Anomalies in the total ozone column

The fig­ure shows anoma­lies in the to­tal ozone col­umn in the years rang­ing from 1960 to 1980. The re­sults of three long-term sim­u­la­tions, pro­duced us­ing the at­mo­spher­ic chem­istry mod­el EMAC (for the pe­ri­od from 1960 to 2100), are com­pared here with match­ing ob­ser­va­tions by US-Amer­i­can and Eu­ro­pean satel­lite in­stru­ments (for the pe­ri­od from 1980 to the present day), op­er­at­ed by NASA or ESA.

The figure shows anomalies in the total ozone column in the years ranging from 1960 to 1980. The results of three long-term simulations, produced using the atmospheric chemistry model EMAC (for the period from 1960 to 2100), are compared here with matching observations by US-American and European satellite instruments (for the period from 1980 to the present day), operated by NASA or ESA.
