The measured frequency, wave normal angle and polarization are consistent with the predictions of a dispersion solver. The magnetospheric plasma contains hot protons (keV), cold protons (eV), plus some heavy ions. While the cold protons follow the magnetic field fluctuations and remain frozen-in, the hot protons are at the limit of magnetization. The cold protons exchange energy back and forth, adiabatically, with the wave fields. The cold proton velocity fluctuations contribute to balance the Hall term fluctuations in Ohm's law, and the wave E field has small ellipticity and right-handed polarization. The dispersion solver indicates that increasing the cold proton density facilitates propagation and amplification of these waves at oblique angles, as for the observed wave.}, organization = {ISSI international team Cold plasma of ionospheric origin in the Earth's magnetosphere}, organization = {Ministry of Economy and Competitiveness (MINECO) of Spain FIS2017-90102-R}, organization = {Centre National de la Recherche Scientifique (CNRS)}, organization = {European Commission}, organization = {Centre National D'etudes Spatiales}, organization = {University of Toulouse}, organization = {National Aeronautics & Space Administration (NASA) 80NSSC18K1378 80NSSC19K070 80NSSC19K0254 80NSSC19K0270 NNG04EB99C}, organization = {SNSA 56/18}, publisher = {Wiley-Blackwell Publishing}, title = {Kinetic Interaction of Cold and Hot Protons With an Oblique EMIC Wave Near the Dayside Reconnecting Magnetopause}, doi = {10.1029/2021GL092376}, author = {Toledo Redondo, S. and Porti Durán, Jorge Andrés and Salinas Extremera, Alfonso}, }
