Observations of interplanetary scintillation (IPS) can be used to provide information on the solar wind at all heliographic latitudes and across a range of distances closer to the Sun than is possible with any current in-situ instrument. The ability of two-site IPS observations to resolve regions of different solar wind speeds improves as the separation of the antennas increases, and measurements of this type can also provide information on equator-wards or pole-wards deviations in solar wind flow (e.g. Moran et al. 1998; Moran 1998). In this paper we discuss recent results from a programme of measurements combining the telescopes of EISCAT and MERLIN, providing maximum parallel baselines of around 2000 km and greatly improving sensitivity to small changes in solar wind speed and direction. The results indicate the existance of two discrete modes of fast solar wind, as well as providing the most accurate measurements to date of meridional flows in the inner solar wind.
