last updated 26 December 2002

Description: The lines show daily average ozone for these regions:

The measurements are satellite based, from NASA's TOMS. Some missing values were filled by extrapolation.

Comments: The period covered by these measurements (6 years) is too short to show long term trends, but this data does show seasonal and short-term variation.

Source: NASA TOMS, on line.
