SUMMARY Mean hourly values of the horizontal and vertical components of the geomagnetic field at six observatories on the Iberian Peninsula were analysed to study seasonal and spatial behaviour of the solar and lunar (ionospheric and oceanic) daily geomagnetic variations. The results are tabulated and their characteristics are discussed. The influence of local oceanic effects on the lunar oceanic contribution at the peninsular observatories is noted. In particular, the spatial behaviour of the lunar oceanic contribution is considered. Whereas the mean value for the Peninsula is consistent with that expected according to an existing model for electric currents in the eastern Atlantic Ocean, individual values are not. The influence of tide in the Mediterranean Sea, of water currents in the Strait of Gibraltar and of local effects in the Atlantic Ocean is proposed as the reason for this behaviour.

[1] This paper presents the results of a scintillation measurement campaign. The receivers used during this campaign were located in five regions of the globe which allowed us to investigate geographic similarities and differences. Most of the receivers were located in the equatorial region, and one of them was located at high latitudes. Significant results were achieved even though the measurement period was around solar minimum. An intercomparison with the Wide-Band Scintillation Model and the Global Ionosphere Scintillation Model has been carried out, and the construction of scintillations maps has been initiated.
