Polar mesosphere winter echoes during MaCWAVE

Autor: S. Kirkwood, E. Belova, U. Blum, C. Croskey, P. Dalin, K.-H. Fricke, R. A. Goldberg, J. Manninen, J. D. Mitchell, F. Schmidlin

Publikováno v: Annales Geophysicae, Vol 24, Pp 1245-1255 (2006)

During the MaCWAVE winter campaign in January 2003, layers of enhanced echo power known as PMWE (Polar Mesosphere Winter Echoes) were detected by the ESRAD 52 MHz radar on several occasions. The cause of these echoes is unclear and here we use obs

The atmospheric background situation in northern Scandinavia during January/February 2003 in the context of the MaCWAVE campaign

Autor: U. Blum, G. Baumgarten, A. Schöch, S. Kirkwood, B. Naujokat, K. H. Fricke

Publikováno v: Annales Geophysicae, Vol 24, Pp 1189-1197 (2006)

The atmosphere background wind field controls the propagation of gravity waves from the troposphere through the stratosphere into the mesosphere. During January 2003 the MaCWAVE campaign took place at Esrange, with the purpose of observing vertica
