      Meteoroids of sub‐milligram sizes burn up high in the Earth's atmosphere and cause streaks of plasma trails detectable by meteorradars. The altitude at which these trails, or meteors,form depends on a number of factors including atmospheric density and the astronomical source populations from which these meteoroids originate. A previousstudy hasshown that the altitude of these meteorsis affected ...

      The mesosphere/lower thermosphere (MLT, 80–100 km) region is an important boundary between Earth's atmosphere below and space above and may act as a sensitive indicator for anthropogenic climate change. Existing observational and modeling studies have shown the middle atmosphere and the MLT is cooling and contracting because of increasing greenhouse gas emissions. However, trend analyses are ...
