A study of seasonal variations of gravity wave intensity in thelower thermosphere using LF D1 wind observations and a numerical model
The data of the regular low-frequency D1 E-region observations at Collm, Germany (52°N, 15°E) in 1983–1999 are used for estimations of the intensity of short-period perturbations of the horizontal drift velocity at 85–110 km altitude. A simple half-hourly-difference numerical filter is used to ex...
