The half duration is fixed to be, where M0 is the scalar moment in N m (Ekström et al., 2005).
The peak enhancement in the neutral density is 21.7%, 13.7%, and 7.1% for the double duration flare, the normal flare, and the half duration flare, respectively.
The peak increase in neutral temperature is 64.5, 42.8, and 22.2 K for the double duration flare, the normal flare, and the half duration flare, respectively.
Dayside average change in thermospheric density (b) and temperature (c) at 400 km. Figure 12b, c shows the dayside average responses of neutral density and neutral temperature to the three solar flares: half duration, normal duration, and double duration.
The temporal of ΔEUV during the three solar flares (normal duration, double duration, and half duration) is illustrated in Figure 12a; that is, the first one has half integrated energy compared to the normal condition and the second one has the double integrated energy.
The temporal variation for the moment-rate function of each subfault is represented by a series of four overlapping triangle functions with 2 s half-durations and 2 s lag offsets.
As for the 19 33 UT event, the moment-rate function of each subfault was decomposed into a series of four triangle functions with 2 s half-durations and 2 s lag offsets.
In Fig. 4, we show the distribution of waveform variance as a function of the half-duration of the source time function (Tr) and the centroid depth.
Moment tensor solutions colored based on their variance as a function of the half-duration of the source time function (Tr) and the centroid depth.
The half-duration of a postjunctional spikelet/AP was measured at the half amplitude of a spikelet/AP.
The bump parameters (amplitude = 3.2 mV, half-duration = 39 ms for the one shown in Fig. 6A) agree with the previous recordings [24].
