Global distribution of electron temperature from Swarm and its possible correction
Original language description
We have analyzed the global distribution of the electron temperature (Te) measured by the Langmuir Probes onnthe Swarm satellites during the years 2014-2017. Comparisons between measured Te and the IRI (InternationalnReference Ionosphere) model (TBT-2012) are presented. We found that the global patterns of Te observed bynSwarm and predicted by IRI are similar, however, substantially differ in absolute values. The magnitude of thendifferences between Swarm and IRI Te dependent on local time and latitude. The smallest differences are observednat high latitudes where the Swarm Te is higher than the IRI Te by about 10%. The largest differences were foundnat low and equatorial latitudes at nighttime, where the Swarm Te is more than 100% higher than the IRI prediction.nTherefore, the IRI Te model is used to correct the Swarm Te measurements by removing the bias as a function ofnlocal time and latitude. The corrected global patterns of Te are analyzed with assistance of the physics based FieldnLine Interhemispheric Plasma flow (FLIP) model and are also compared to other measurements (e.g., CHAMP,nFPMU onboard ISS etc.).
