Short summary
The phenomena of meteors occurs at altitudes of 60–120 km and can be used to measure the neutral atmosphere. We use a large high power radar system in Norway (Middle Atmosphere Alomar Radar System (MAARSY)) to measure the meteors and determine changes to the atmospheric density between the years of 2016–2023 at altitudes of 85–115 km. The same time period between years are compared, minimizing changes to the measurements due to factors other than the atmosphere.
