The mesospheric responses to short-term solar ultraviolet variabilityThe response of mesospheric ozone and temperature to short term solar ultraviolet variations related the the 27 day rotation of the Sun has been recently detected from analysis of satellite measurements. A systematic depletion of ozone was detected near 70 km, which is attributed to solar Lyman alpha photodissociation of water vapor with subsequent catalytic destruction of O(x) by HO(x) and temperature feedback effects resulting from the unexpectedly strong temperature/UV response near 70 km. The nature of latitudinal and semiannual variations in the ozone/UV and temperature/UV response were isolated. Observed variations are compared to theoretical models.
