Figure 8From: Response of the mesosphere-thermosphere-ionosphere system to global change - CAWSES-II contribution Long-term trends in hmF2 and foF2. Long-term trends in hmF2 (top panel) and foF2 (bottom panel) for Slough/Chilton (51.6N, 358.7E) with solar activity correction with F10.7 or with sunspot number R. ΔhmF2 and ΔfoF2 are differences between observed values and empirical model with F10.7 (R) and geomagnetic activity. After Bremer et al. ([2012]).Back to article page
