Determination of the Trace-Gas Concentrations at the Altitudes of the Lower and Middle Mesosphere from the Time Series of Ozone Concentration

Resumo

We present a statistical (Bayesian) approach to retrieving the concentrations of the most important mesospheric trace gases at altitudes of 50–75 km using the photochemical model based on the time series of ozone concentration, which are measured during the daylight hours in one day with the help of the ground-based passive microwave devices. Using the model noisy time series of ozone concentration with allowance for the realistic accuracy of its measurements in the mesosphere, which is ensured by the available ozonometers, the accuracy of retrieving the non-measurable mesospheric characteristics is studied as a function of the altitude and the time-series length.
