| Zusammenfassung |
| Radar wind observations at frequencies between 1.98 and 53.5 MHz obtained at
polar latitudes were compared to in-situ wind measurements by radiosondes at
tropospheric altitudes and to winds from falling spheres at mesospheric
altitudes. Comparisons are shown for several campaigns of radiosonde and
falling sphere observations. The radar wind directions agree well to the
radiosonde and falling sphere observations and are highly correlated. The
winds estimated from radar measurements are less than the radiosonde data by
about 15% for spaced antenna observations and by about 10% for the Doppler
beam swinging experiment. At mesospheric altitudes the spaced antenna winds
obtained from the wide-beam Andenes MF radar are underestimated in the order
of 35% and winds from the narrow-beam Saura MF radar are underestimated by
about 20% compared to falling sphere winds at altitudes between 70 and
80 km. Furthermore, the relation between wind measurements using narrow-beam
and wide-beam antenna arrangements for the MF radars is discussed and VHF
radar observations are compared to the wide-beam MF radar. |
