Numerical evaluation of the role of surface layers of the solar atmosphere in the blanketing effect.

The role of surface layers of the solar atmosphere (tau = 10 to the -8th to 0.1) in the blanketing effect is investigated for the example of the Harvard-Smithsonian Reference Atmosphere. It is shown that in this model the effect of absorption lines on continuous radiation at tau = 0.0001 leads to a 410-K decrease in temperature, while at tau = 1.0 this effect leads to a 360-K increase in temperature. It is found that at values of tau up to 0.01 the edge blanketing effect produces a 25% change (in comparison with the total value) in the numerical value of the source function.
