Electron temperature data obtained aboard two satellites are compared with the IRI model. Our comparison may serve as an input to a future version of IRI. HINOTORI data show IRI90 to predict night time Te quite well with the exception of a few peculiar phenomena, in particular a morning overshoot at height around 600 km and anomalous Te observations of AKEBONO for the first time allowed to extend reliably the temperature profile up to - 8000km. This profile clearly depends on local time at all invariant latitudes. The data suggest strong influence of solar activity on electron temperature.
