Ionosphere morphology
Web11 jun. 2024 · Solar activity dominates the temporal variability of ionospheric properties, which makes it difficult to identify and isolate the effects of geomagnetic activity on the ionosphere. Therefore, the latter effects on the ionosphere are still unclear. Here, we use the spectral whitening method (SWM)—a proven approach to extract ionospheric … WebThus, we divided observations of FY3C/GNOS and COSMIC into four seasons , ME-month (±45 days to March equinox of 2016), JS-month (±45 days to June solstice of 2016), SE …
