Observation Site: TRF - Tromso Norway MF Radar
Instrument Page: TRFDescription:
The Tromso MF radar is located in Norway (70 N, 19 E). The mean solar local time (SLT) is Universal Time (UT) plus 1 hour and 18 minutes. (SLT = UT + 1:18). The phases are in SLT and the measurement days start at 0 UT. The Tromso MF radar data is obtained and analyzed by the Saskatoon MF radar scientists, and has provided considerable mean winds (Manson et al., 1990a and 1991a) and tidal data (Manson et al, 1989). LTCS-1 and LTCS-2 are described for all middle atmosphere radars in Manson et al. (1990b, 1991b). MF radars use the spaced antenna method. Harmonic analysis is applied to hourly mean winds (weighted by data yield per hour) at individual heights to obtain tides for the prime LTCS or stated intervals. Typical standard deviations for means, 12-hour and 24-hour tides are in the above LTCS papers. Tides of the month for Tromso are means of 4-day fits (the amplitudes are arithmetic means). Data up to 99 km are real heights --- above, they are from the E-region, a layer about 5 km centered near 102 km.
