Mesospheric temperature estimation from meteor decay times during Geminids meteor shower
Meteor radar observations at the Sodankylä Geophysical Observatory (67° 22′N, 26° 38′E, Finland) indicate that the mesospheric temperature derived from meteor decay times is systematically underestimated by 20–50 K during the Geminids meteor shower which has peak on 13 December. A very good coincide...
