Abstract Simulations based on physical models of the thermosphere‐ionosphere system suggest that the ionosphere will sink as the thermosphere cools and contracts in response to increasing greenhouse gas concentrations. As a consequence, long‐term

Several total solar irradiance (TSI) satellite missions have been carried out since 1978. None of these missions have lasted more than one to two solar cycles (SCs), and each mission implies a slightly different absolute TSI baseline. Nonetheless, se

Climate change is characterized by global surface warming associated with the increase of greenhouse gas population since the start of the industrial era. Growing evidence shows that the upper atmosphere is experiencing appreciable cooling over the l

The Earth’s ionosphere presents long-term trends that have been of interest since a pioneering study in 1989 suggesting that greenhouse gases increasing due to anthropogenic activity will produce not only a troposphere global warming, but a cooling

We analyze the auroral boundary corrected geomagnetic latitude provided by the Auroral Boundary Index (ABI) database to estimate long-term changes of core origin in the area enclosed by this boundary during 1983–2016. We design a four-step filterin

The effect of including solar cycle 19 (1954-1964) in ionospheric trend estimation is assessed using experimental foF2 values. The dominant influence on the F2 layer is solar EUV radiation. In fact, around 90% of inter-annual variance of ionospheric

Ionospheric effects of Mount Pinatubo volcanic eruption in June 1991 were recorded on 1-minute interval soundings made by stations north of the volcano. Disturbances characterized by quasi-periodic wavelike trains were detected. They were attributed

A search for a relationship between tropical stratosphere temperature anomalies at 10 hPa (~30 km), during 1964-1996 and the F10.7 cm solar flux has been carried out. The long-term trend and the Quasi-Biennial Oscillation influence over four seasonal

Chen (1992) reports an association between the variance of the F2 layer critical frequency, foF2var, and the quasi-biennial oscillation, QBO, of the monthly mean zonal wind in the equatorial stratosphere (MMZW) at 40 mb, with data of March and Septem
