In this paper we present the first high-resolution E region neutral wind measurements made at the Chatanika. Alaska, incoherent scatter radar facility. The high-resolution (~10 km) measurements are made possible by a new digital correlator system that is now fully operational. Daytime measurments show that the neutral transport in the low E region follows the general pattern of the global pressure-driven winds. However, above 110 km there is evidence that the neutral winds are being influenced by electric fields associated with daytime precipitation events. Data taken during a moderately disturbed nighttime period show an equatorard neutral wind component above ~115 km during the evening eastward electrojet and poleward component through the morning westward electrojet. In our analysis we have emphasized the critical dependence of the neutral wind estimates on the collision rate parameter, particularly above ~120 km, where ion-neutral collisions rapidly diminish.
