Includes bibliographical references. "The International GNSS Service final global maps of Total Electron Content (TEC) from 2000 to the end of 2010 have been analyzed. This period covers the last sunspot cycle, including its highest and lowest ionospheric activity periods, as well as the first year of the current cycle. Global and latitudinal statistics of TEC over this period are derived and presented. Strong correlation between daily international sunspot numbers and daily mean TEC can be seen in the data sets studied"--Abstract, page 1. Canada. Natural Resources Canada. Geomatics Canada.
