Abstract Measurements of the total column amount of ozone from the Total Ozone Mapping Spectrometer (TOMS) on the Nimbus 7 satellite have now been made for 13 years. They show that the 1991 Antarctic ozone hole again had a pronounced minimum in early October; making four of the last five years with deep ozone holes. Global scale measurements by TOMS show no trend in total ozone near the equator, but a significant trend at northern middle and high latitudes. This trend has a pronounced seasonal variation with maximum in winter. The observed trend is significantly larger than the predictions of gas‐phase photochemical models.
