During the winter when there are no flights into Pole, these data are stored until opening then they are mailed out. After the data has been processed and analyzed, each group within CMDL will publish their results. CMDL is currently in the process of placing their data on the World Wide Web. In the future, it is planned that all our data sets will be available on the Web. First of all there are special conditions that exist at the South Pole which make it an ideal location for monitoring the composition and behavior of the atmosphere for identifying climate predictor.
Local contamination is minimal as are regional-scale sources and sinks.
The nearest urbanization is 3000 miles away and the nearest land biota is 2500 miles away. Because contamination sourses are distant, the air measured at the South Pole is very well mixed and is extremely clean. When compared to measurements made elsewhere around the globe, it is the background air of the planet. There is a very high frequency of wind from the Clean Air Sector. Data capture is very high and collection of a long term continuous record is greatly facilitated.
