GPS (Global Positioning System) Radio occultation (RO) measurements from CHAMP, GRACE and\udFORMOSAT-3/COSMIC satellites at Northern Hemisphere midlatitides (50°–55° N)\udare analysed to obtain the diurnal variation of sporadic E layer occurrence frequency in\ud2006 and 2007. Interconnections with zonal wind shears measured by meteor radar at Collm\ud(51.3° N, 13° E), Germany, are investigated. According to theory, maximum\ud<I>E<sub>s</sub></I> occurrence is expected when the zonal wind shear, which is mainly produced by the\udsemidiurnal tide in midlatitudes, is negative. This is confirmed by the present\udmeasurements and analysis
