Fig. 5.From: Polar cap ionosphere and thermosphere during the solar minimum period: EISCAT Svalbard radar observations and GCM simulationsMonthly-averaged ion temperature obtained from the ESR observations (green line) and the ion temperature from the IRI 2007 model (black line) in March. The error bars of the ESR ion temperature are the standard errors of the mean. In addition to the ion temperature, the neutral temperature obtained from the NRLMSISE-00 model is also shown (blue line).Back to article page
