The use of interplanetary scintillations for probing otherwise inaccessible regions of the solar wind is reviewed. A comparison with space-craft observations in the ecliptic is used as a calibration for the scintillation observations. Recent observations at high latitudes and near the Sun are discussed from this viewpoint. A new analysis which uses both scintillation and angular scattering observations to estimate the electron density spectrum is introduced. The spectrum appears to have a high frequency ‘cutoff’ which varies slowly with solar distances and may also have a relatively flat region just below the cutoff frequency.
