Extended Data Fig. 6: Radar measurements from the EISCAT Radar in black compared to in situ measurements by the SLP instrument in gold.
From: Earth’s ambipolar electrostatic field and its role in ion escape to space
a,b, Plasma density; c,d, Electron temperature. e,f, Ion temperature; g,h, Ion velocity. These plots were made by time-averaging measurements from the upleg and downleg portion of the flight. Error bars represent the standard deviation. EISCAT data were truncated above 500 km in Fig. 3 owing to the large error bars but are shown here in full. The good agreement between independent measurements of \({n}_{e}\) and \({t}_{e}\) by EISCAT and SLP give good confidence in our SLP data analysis.
