Surface ozone data of Mauna Loa and the other 14 monitoring sites of altitude lower than 1000 m in the northern hemisphere were used to give a joint discussion for the distribution and variation features of surface O3. The data, based on ground observation, were collected, processed, and distributed by WDCGG (World Data Centre for Greenhouse Gases) in GAW. The monthly mean and hourly data of surface ozone in these 15 sites were analyzed to sum up the difference of surface ozone annual and seasonal variations in different areas of the northern hemisphere.
