Short summary

This study shows the width of the meteor height distribution (FWHM) is well correlated with the atmospheric pressure, not only experimentally but theoretically. From the correlation analysis, we found that the FWHM provides the best estimation of the temperature at the height layer below the meteor peak height by 2–3 km. We also proved a meteor echo height ceiling effect (MHC) is primarily controlled by the atmospheric conditions, and this enables the FWHM to estimate the temperature accurately.
