摘要: THE daytime ionosphere of Venus is observed between 100 and 500 km altitude has a peak electron concentration 5 × 105 cm−3 at 140 (ref. 1). Below 200 CO2+ thought to be the principal ion2,3 unless oxygen present. I suggest that altitudes less than 130 · CO2 an important ionic constituent ionosphere. ion clustering processes combine with low temperature mesopause form coagulates giving rise ultraviolet haze layer which frequently been observed.
