For the first quarter of this year total column ozone values at Macquarie Island remained slightly lower than average for the period 1985 to 2001. Since then daily values have gradually increased to slightly above average. It is too early to say if this is an indication of a recovery of the ozone layer or just an aberration due to the El Nino year we are experiencing. Note the data before 1985 is not traceable to our Regional Standard Dobson. While the pre 1985 data remains the best estimate of data available, there were known problems that are unlikely to be addressed properly for many years.
