To investigate possible couplings between planetary waves and the semidiurnal tide (SDT), this work examines the statistical correlations between the SDT amplitudes observed in the Northern Hemisphere (NH) mesosphere and stationary planetary wave

Latitudinal wave coupling of the stratosphere and mesosphere during the major stratospheric warming in 2003/2004

Publikováno v: Annales Geophysicae, Vol 26, Pp 467-483 (2008)

The coupling of the dynamical regimes in the high- and low-latitude stratosphere and mesosphere during the major SSW in the Arctic winter of 2003/2004 has been studied. The UKMO zonal wind data were used to explore the latitudinal coupling in the

Seasonal variations of the semi-diurnal and diurnal tides in the MLT: multi-year MF radar observations from 2–70° N, modelled tides (GSWM, CMAM)

Autor: A. H. Manson, C. Meek, M. Hagan, J. Koshyk, S. Franke, D. Fritts, C. Hall, W. Hocking, K. Igarashi, J. MacDougall, D. Riggin, R. Vincent

Publikováno v: Annales Geophysicae, Vol 20, Pp 661-677 (2002)

In an earlier paper (Manson et al., 1999a) tidal data (1990–1997) from six Medium Frequency Radars (MFR) were compared with the Global Scale Wave Model (GSWM, original 1995 version). The radars are located between the equator and high norther

Large amplitude quasi-periodic fluctuations associated with a mid-latitude sporadic E layer

Autor: C. Huang, Wesley E. Swartz, D. Riggin, Jason Providakes, Michael C. Kelley, R. F. Pfaff

Publikováno v: Journal of Atmospheric and Terrestrial Physics. 57:1165-1178

For the first time a sounding rocket has been launched into a mid-latitude sporadic E event which was shown to be the source of VHF radar echoes. The layer had a very high peak electron density (∼10 6 cm −3 ) and was thicker (∼5 km) than most e

Continuous measurement of stimulated electromagnetic emission spectra from HF excited ionospheric turbulence

Autor: R. Massey, J. Stanley, W. T. Armstrong, M. McCarrick, P. Y. Cheung, D. Riggin, P. Argo, Robert C. Carlos, A. Y. Wong

Publikováno v: Radio Science. 25:1283-1289

Stimulated electromagnetic emissions of the auroral ionosphere in the vicinity of Fairbanks, Alaska, have been observed during high-power HF heating experiments. Asymmetric spectra around the heater frequency with dominant lower sidebands are observe

A 360deg Digital Phase Detector with 100-kHz Bandwidth

Autor: R. S. Biddle, R. D. Patton, Michael V. Fazio, D. W. Reid, D. Riggin, H. A. Jackson

Publikováno v: IEEE Transactions on Nuclear Science. 28:2158-2159

The general availability of digital circuit components with propagation delay times of a few nanoseconds makes a digital phase detector with good bandwidth feasible. Such a circuit has a distinct advantage over its analog counterpart because of its l
