Based on extensive, diagnostic ground observations in the Svalbard area mainly at Ny Alesund at 76 deg A together with simultaneous, coordinated measurements from east Greenland the EISCAT radars as well as DMSP satellite- recordings, structures and dynamics of the dayside cleft and polar cap region have been obtained. This is an important prerequisite to the understanding of the physics of dayside boundary layers processes. Several papers have been published, many lectures given and a NATO Advanced Workshop related to this program arranged. Possible generation mechanisms of dayside cuspcleft auroras including magnetic merging, external pressure pulses, Kelvin-Helmholtz- instabilities, and dynamo processes by intruding plasma elements are discussed. Characteristics of these boundary layer processes and their ionospheric effects are a major objective of these studies. The Fast Explorer project as well as the new EISCAT radar.
