Julia radar studies of electric fields in the equatorial electrojet.==$Geophysical Research letters, 24$==(13), 1687-1690. https://doi.org/10.1029/97GL00373index-oti2018http://hdl.handle.net/20.500.12816/593First results from the JULIA radar at Jicamarca are presented. These include coherent scatter observations of the equatorial electrojet and of 150-km echoes. Interferometry is used to measure the zonal drift rate of kilometer scale waves in the electrojet as functions of altitude. A technique for estimating the background zonal electric field from the interferome­try data is described. The electric field estimates can be calibrated against the Doppler speed of the 150-km echoes when the latter are present. The kilometer-scale wave drifts sometimes exhibit large-amplitude, periodic height variations with vertical wavelengths of about 10 km. These signatures are reminiscent of the wind pro­files measured with chemical release techniques in the lower thermosphere during the Guará campaign.application/pdfenginfo:eu-repo/semantics/openAccessElectric currentsElectric fieldsInterferometryRadar measurementRadar systemsAtmospheric electricityInterferometryIonosphereRadarinfo:eu-repo/semantics/articlehttp://purl.org/pe-repo/ocde/ford#1.05.01Geophysical Research Lettershttps://doi.org/10.1029/97GL00373
