The nighttime distribution of ozone in the low-latitude mesosphere

摘要: The intensity of stars at wavelengths in the Hartley continuum region ozone has been monitored by University Wisconsin stellar photometers aboard OAO-2 satellite during occultation star earth's atmosphere. These data have used to determine number density profile tangent point. nighttime a bulge its vertical with peak 1 3×108 cm−3 approximately 83 km and minimum near 75 km. high altitudes varies as much factor 4, but does not show any clear seasonal variation or variation. retrieved profiles define envelope that is compared other observations also results theoretical models.
