The Global OzoneObserving System (GO3OS) consists of more than 140 monitoring stations of total ozone, the largest number of which is being located in the middle Northern latitudes, while the operation of these stations is being conducted using the following instruments:

• Dobson spectrophotometer
• Brewer spectrophotometer
• Filter Ozonometer ( M-83, M -124)

In the following table there are available for each station the results of the comparisons with the GOME GDP4.0 level-2 total ozone data.
