Microwave and optical observations of ozone and temperature of the middle atmosphere during stratospheric warming in Western Siberia

We present the results of combined ground-based measurements of vertical ozone and temperature profiles with the use of microwave and lidar instrumentation during stratospheric warming. Marked variations in ozone concentration and temperature in the middle atmosphere are recorded during wintertime warming (December, 2012–January, 2013). The ozone concentration at altitude levels from 25 to 60 km increased by a factor of 1.5–2, with the amplitude of ozone variations substantially increased. The peak of the positive deviation of temperature from the monthly average value reached 70 K at a height of 30 km. The daily variations in ozone at a height of 60 km, associated with sunset and sunrise, were about 30%.
