Modeling of the lower ionosphere climate

Abstract A coupled model of the troposphere-stratosphere-mesosphere and the ionospheric D region (for 0–90 km altitudes) is presented. The model is based on a three-dimensional general atmospheric circulation model in a hybrid coordinate system. A five-component model has been taken as a photochemic...

Abstract A coupled model of the troposphere-stratosphere-mesosphere and the ionospheric D region (for 0–90 km altitudes) is presented. The model is based on a three-dimensional general atmospheric circulation model in a hybrid coordinate system. A five-component model has been taken as a photochemical model for the lower ionosphere. The role of the neutral atmosphere thermodynamic characteristics in the formation of the D layer mean state has been investigated by the model results. Based on a preliminary model identification using direct measurements, and radiowave absorption and propagation, it has been indicated that the model satisfactorily reproduces climatic characteristics of the ionospheric D layer.
