Sen, Hari K. Abstract Radio observations of the quiet sun indicate an electron temperature I0,0000K for the lower chromosphere, whereas optical observations of the widths of chromospheric emission lines indicate a temperature > 30,0000K. An attempt is made in this paper to reconcile these two apparently conflicting observational results by the physical picture of a "two-temperature" atmosphere in a shock front. It is shown that the shocks caused by the photospheric granules may be frequent enough to overcome the effects of collisions and preserve a quasi-steady state, nonMaxwellian electron velocity distribution in the high, and possibly even in the low chromosphere.
