| Zusammenfassung |
| Polar Mesosphere Summer Echoes (PMSE) are observed with 50-MHz VHF radars at various
locations in the Northern Hemisphere for more than 20 years. Continuous and homogeneous
observations of PMSE have been done on the North-Norwegian island Andøya (69.3∘N,
16.0∘E) from 1999 until 2009 using the ALWIN radar and since 2011 using the Middle
Atmosphere Alomar Radar System (MAARSY) at the same location. In 2011 the PANSY
radar - a Mesosphere-Stratosphere-Troposphere/Incoherent Scattering (MST/IS)
radar - was installed at Syowa Station, Antartica (69.0∘S, 39.4∘E) and continues
observation of PMSE were started in the austral summer period 2013/2014. Since both
MAARSY and PANSY are high-power-large aperture radars mesospheric echoes
are observed almost continuously during the summer seasons in the Northern and
Southern Hemisphere now. We present a first comparison of PMSE observations
obtained at both radar sites during a period of 6 boreal summers (Andøya, NH)
and 3 austral summers (Syowa, SH) and discuss similarities and differences of
seasonal and diurnal variations of PMSE occurrence frequencies and echo intensity. |
