The average, longterm behaviour of many parameters P of the Earth's atmosphere and ionosphere depends on the solar activity cycle. In many cases it can be roughly described by a linear approximation of the form P = P0(1 + kR), where for example, P is electron density of the ionosphere or stratospher

By means of an inversion of H and K Ca II line profiles the temperature and electron density in the chromosphere above the umbrae of two sunspots have been estimated. The temperature gradient 5 K km -1 exceeds the corresponding values in both quiet regions and plages. At a height of about 1500 km th
