Abstract

DURING the period between ground sunset and ionospheric sunset, the solar light is considerably filtered during its passage through the entire atmosphere before reaching still-illuminated ionospheric regions. Most of the ionizing radiation is absorbed before it reaches the illuminated regions, hence only some heating might be caused by the long-wavelength spectrum of the incident radiation. It seems reasonable, however, to expect that topside regions are thermally stable because they have been illuminated for a long period of time.
