Comparing high-latitude thermospheric winds from Fabry-Perot interferometer (FPI) and challenging mini-satellite payload (CHAMP) accelerometer measurements

<p>It is generally assumed that horizontal wind velocities are independent of height above the F&lt;span classCombining double low line"inline-formula"&gt;1&lt;/span&gt; region (&amp;gt;300km) due to the large molecular viscosity of the upper thermosphere. This assumption is used to compare two completely different methods of thermospheric...
