Abstract

The talk presents new results on the verification of the global atmosphere-ionosphere model WACCM-X using radiophysical data from the "Mikhnevo" midlatitude geophysical observatory (IDG RAS). VLF stations records and Schumann resonances evidence were used. The model failed in reproducing VLF amplitudes and phases temporal dynamics. The magnitudes of Schumann resonances are overestimated (1-3 Hz). The performance of the global model is insufficient and further elaboration is required.
