Abstract

The ionospheric response to solar extreme ultraviolet (EUV) variability during 2011 - 2014 is shown by simple proxies based on SDO/EVE solar EUV spectra. The daily proxies are compared with global mean total electron content (TEC) derived from GNSS TEC maps and Tthey describe about 76% of the intra-seasonal TEC variability. At time scales of the solar rotation and longer, there is a time lag between EUV and TEC variability of about one day, indicating dynamical processes in the thermosphere/ionosphere system that leads to delayed atomic oxygen variation in the ionospheric F2 layer.
