Fig. 6From: Improving the estimation of thermospheric neutral density via two-step assimilation of in situ neutral density into a numerical modelEach panel contains time series of neutral density \(\left( \frac{\text {g}}{\text {cm}^3}\right)\) for different cells of the data grid. Each row corresponds to a geocentric latitude and each column to an ellipsoidal height. The longitude is always \(0^{\circ } E\). The panels of each column share the same y-axis. The errors bands show the standard deviation. This figure shows the first 2 days of the experiment with quiet geomagnetic conditionsBack to article page
