Abstract: Polar mesosphere echoes and polar mesosphere clouds data extraction and analysis software (PMEC_DEAS) is used to deal with the echoes and clouds dataset, then the characteristics of radar echoes are studied in the paper. By analyzing the polar mesosphere summer echoes (PMSE) and polar mesospheric clouds (PMC) data in the short-and long-terms as an example based on the PMEC_DEAS, the correlation between the occurrence rate (OR) of PMSE and PMC is studied. It is found that the correlation between the short-term PMSE OR and PMC is not significant, the long-term double-layer PMSE OR is positively correlated with the PMC. It shows that double-layer PMSE is closely related to PMC, which is consistent with existing conclusions. PMEC_DEAS can effectively adapt to the complex characteristic changes of the events and has good robustness. The data analyzed by PMEC_DEAS exhibit better stability and compatibility, and show superiority in convenience and utilitarian nature over the current mainstream software.
